Chevrolet - Trailblazerext :: 2006 - Gas Gauge Sensor Not Working?
Jun 13, 2013
The gas gauge is not working properly. Two years ago it began to move to empty when I would fill the tank up. Then, without explanation, it worked fine until three weeks ago. I was traveling on the Mass Turnpike when the check engine light came on and the gas gauge showed that I had a full tank, when I knew that I had less than half a tank based on the mileage. I took the car to have the code read and discovered the gas gauge sensor was not functioning correctly, the ABS sensor coded, and the coolant system showed a code as well. I took the car to a mechanic who checked out the electrical system and said that he found no problem. I then took the car to another mechanic who immediately said it could be an electrical problem or the fuel pump. The fuel gauge still doesn't work correctly. I did not have this mechanic look at the car. I filled up the tank and the indicator went to empty immediately. My question is, if the fuel pump is the problem, would it take two years for the pump to malfunction? What else could the problem be, and why doesn't the mechanic just replace the sensor? No one seems to be concerned about the other two codes for the ABS system and the coolant system. I also should mention that the engine now sounds like a diesel engine on a tractor trailer revving up before you switch gears. I don't remember the car ever sounding like this before. Also the vehicle has 120,000 miles.

My trailblazer started with the spitting and sputtering (misfiring) last week. Over 100,000 miles on it, ya, in need of a tune up. So for obvious reasons new spark plugs seemed to be the logical choice. If it wasn't the problem, it can't hurt to change them. Truck's SES light did not come on, but truck was running pretty crappy, more when it was cold than hot, but definetely a loss of power. There is also a slight exhaust leak starting, where abouts right now I haven't pinpointed, deaf in one ear so it's hard to tell where it is coming from.
So I had my brother in law install the new spark plugs. We took the old ones out and 4 and 5 cylinder plugs had oil on them. Ah great, valve cover gasket and the gaskets the spark plugs sit on (don't ask me, not a mechanic lol) need to be changed. Started with just the plugs for now. Started truck up, still had a bit of vibration on idle, like it would from an exhaust leak, but still didn't seem right . But an even more noticable loss of power when driving, truck doesn't seem to want to get above forty.
Now my SES light is flashing almost consistently unless I'm stopped (idled). It almost feels like the cat is clogged. Did smell a heavier than normal gas smell when changing out the plugs. I know that the flashing SES almost certainly means a misfire. But why would it all of a sudden come on after changing the plugs? Tomorrow I am going to my friends garage who has the scanner tool (not just the one that reads codes) to see if it is a bad coil pack and to see if there is a specific cylinder that is misfiring.
But there is something about that exhaust leak that is leading me to believe it is the culprit of my problems. Leak came first, then the misfiring. Could the cat be clogged, which blew a hole in the exhaust and cause a misfire? And the new plugs just made the misfiring worse to cause the SES light to come on? Is there anything else I should check besides a faulty coil pack and compression check (even though I should have done that when I changed the plugs, but live and learn).

My 2001 Malibu v-6 temp gauge is not working. I have replaced the temp sending unit and it works for a few weeks unit it goes out. What keeps killing the temp sendor?

I have a 2003 Impala with about 122,000 miles on it. On my recent fill up I by accident put in mid grade over the normal unleaded, now I now that won't cause any engine issues that I am aware of, but after doing this fill up my gas gauge is not working properly. When I start the car in the morning the gauge will go to where it should given the mileage I have driven to this point but as I drive the car the gauge goes up to almost full then down some but never back to where it should be. what might be causing this floating incorrect reading by my gas gauge.

2002 ford sport trac.I have been having an ongoing issue that started with the engine cranking but would not turn over until an hour passed. After replacing multiple parts (cam shaft sensor, crankshaft sensor, ignition pack) I am now down to poor fuel economy as the last of the issues (roughly 12 in the city and 15 highway). I was told the issue may be the engine coolant temperature sensor going bad so I decided to replace it. I found this was very difficult due to it being a plug and locking pin design and in a very tight spot in the engine.
I tried to purchase a replacement and the parts store kept trying to insist on selling me a part with threading. I finally found someone that figured out the issue and found the part for the 2001 sport trac had the same plug style with clip that did fit but was shaped a little different on the sensor end which I assume was due to being aftermarket. I noticed that there were two plugs side by side and the one easiest to access was on the left and I was told the one on the right was the sensor that gave the temperature reading to the gauge.
After installing the engine coolant temperature sensor I found the temperature gauge on the dash now will not respond and is sitting below the cold end of the gauge completely off. Is it possible this is because the part was for a 2001? Is the sensor on the left (passenger side) the engine coolant sensor?I would hate to put the old sensor back in just to test if that's the issue due how difficult it was to put that locking pin back on. What to check that could resolve the gauge issue before pulling this sensor back out?

My 2007 Chevy Impala has developed a brand new problem today. Driving down the block to the store, the speedometer started fluctuating wildly. I was going a consistent speed of about 10 mph in my parking lot and when I braked to a stop the speedometer started swinging all over the place, from 10 to 35 mph. It then gave me a message on the dash saying "Speed Limited to 107 MPH" and somehow killed my accelerator because the gas pedal no longer did anything. I restarted the car and the accelerator worked again for a bit and then pulled the same problem again. The speedometer is now fluctuating wildly the entire time I drive, including while stopped, but so far the message seems to have kicked on and disabled my accelerator only when slowing to a stop and accelerating out of a stop (it happened three times).
I know that the Impala's governor is set to 107 mph so I can guess why that message exists, but I wouldn't think a governor would actually kill the car even if it kicked in at the right speed.
It wasn't that long ago that we had to have our pedal position sensor resynchronized and the mechanic had mentioned that it was possible the sensor was going bad, but I don't think that would be the problem here as it seems like the car would actually have been accelerating sporadically, whereas in my case just the speedometer is swinging around despite an even speed.

I am trying to sell my 06 A6 and my check engine light came on. Took it to a certified mechanic and they said don't worry about it's nothing serious maybe a sensor. I then took it to an Audi dealer and they said an evaporation sensor possibly then twisted the fuel cap and it turned off.

The ambient temp gauge on my '07 Santa Fe stopped working, all I was getting was flashing bars across thee bottom. Someone in a thread said there was a TBS about that. I went to my Hyundai dlr and got a copy of the TSB. It was actually pretty easy to take everything apart. The problem was that there were no wires the color I was looking for, also, there were no wires connected to the terminal as shown in the TSB. I went back to my dealer, and after a little research, found that the TSB did not pertain to my car because it was a late model year production. I was told that to fix the problem on my car, all for the fuse blocks would have to be replaced. Shortly after that, I started getting erroneous readings, eg:126 degrees. Now it is reading correctly, but who knows for how long.

All of my interior lights went out. Except for dome lights etc. Here's a more detailed description. Every light effected by the dimmer on the left side near the ECS button don't work. I'm assuming it's a fuse.
Cluster gauges still work fine. The lights just don't work.
Note: Both headlights are out so I don't know if that could be connected in some way. Haven't been able to change them yet.
So, which fuse this would be? I can't seem to find it. Or if it could even be a fuse?

I am working on my dads 06 F350. He had four dash lights go out, so we changed out the bulbs and put the dash back together. When we hooked the batteries back up all the gauges reset except the the boost gauge. The needle went way past 0 and bounced for about 2 seconds then it just stayed below 0. We have tried to reset it by unhooking the batteries and turning the ign. switch on and off several times. Always go back past 0 and stays there. It does work it just doesn't read correctly. I am pretty sure that the needle did not get turned on the shaft? Is there a way to reset it?

I recently purchased a 2006 GS 300 AWD from a friend with about 90k miles. After getting accustomed to this vehicle, I began to notice that the driver's side door handle does not automatically unlock the door as I know it should.
I've troubleshooted and changed the settings for each door handle through the key fob to unlock every door instead of just the drivers door. Every other door handle sensor works, besides the drivers door. I can lock and unlock doors with every other door handle but can not lock or unlock from the drivers side door sensor or the button on the door handle.
I've changed my key fob battery as I read that that might have something to do with it, but alas, no luck and I doubt that was the problem since the other doors have worked fine since I've gotten the car.
Do the sensors on these door handles go bad? Is there a way to replace them and are parts/labor expensive?

We have an 06 Equinox, and lately the low beams have been working intermittently. Also, I don't think the running lights are working either. Low beams don't work on auto or in the "on" position. The high beams do work. We took it to the dealership yesterday and they said we had a bad resistor and replaced it for $270. Tonight my wife tried to drive home after dark and no headlights. She has to take this vehicle on a business trip soon.

My '06 Trailblazer has apparently blown out the fuel gauge sensor. it was erratic then stayed on "E' for two months. So I get to drop the tank to check it... how to check it easily. So I'm figuring if I'm going to drop the tank maybe I should just get a pump and sensor replacement. It has 150 k.

In the last 24 hours my fuel level sensor is failing intermittently. After filling yesterday the fuel gauge went to zero and the MFD read "---" for any range or fuel calculations. Rebooted the car ( ) and it came back on, then off again. today it seems to be working, but I'm waiting for the other shoe to drop.

Noticed today that when I was in a parking garage the gauge lights were off, but when I pulled out into the sun they slowly illuminated. This must mean there is an ambient light sensor, which I didn't know, and can't that be tapped for an automatic headlight retrofit?
Have a 2011 TDI is that matters.....

I need to install an oil pressure sensor sending unit. I've already occupied the 1/8"NPT test port on the rear of the oil cooler, where else might I be able to tap into oil pressure? (LPOP)

So, recently acquired my grandpa's "old" 2000 F250 with the 5.4. I am a pretty mechanical guy, not a mechanic, but not dumb and change my own parts for a lot of stuff. Anyways, when I got the truck, I noticed it didn't like to get warm, or so the gauge said. It would go a little above cold, but you could tell, not a normal reading. I did a coolant flush because the system desperately needed it, changed the tstat, and a few days later, changed the Coolant Temperature sensor.
I pulled the old one out, it was covered in amazing crud from many years of being in there. Slapped the new one in, nothing. Doesn't register on the gauge at all, in fact the gauge acts like it is a dead gauge. I thought it might be the sensor, so I popped the hood again and found I had managed to break the plastic plug on the sensor. Figured that was probably the issue and went and got another. Same result. Checked the connection, it is in there snug. Didn't reset the PCM when I changed the sensor and some vehicles can be finnicky about that.

I just purchased a 2005 Malibu Maxx about three months ago; it only has 19,000 miles on it. The fuel gauge never goes beyond 3/4 when I fill up. It does go down as I drive, so it seems to be working other than not registering full. A friend suggested trying Seafoam. Is this fuel gauge problem something to worry about? Or should I just keep driving and not worry about it?
