Subaru - Engines - Sensors - Loyale :: 1992 - Check Engine Light Won't Go Off?


Feb 11, 2011

my 92 subaru check engine light has been on for months. I took it to my mostly-trusted mechanic. He hooked it up to the computer and the car did not give any codes. He reset the light, but it came right back on when started. I am wondering about the coolant temp sensor but I would expect that would give a code. Why won't a check engine light give a code?

Subaru - Loyale :: 1991 - Bad Gas Mileage In The Cold

My 91 Subaru Loyale is killing me!

When it gets cold, and it is cold in Colorado 9 months a year, my gas mileage drops from 30mpg to 22mpg. It is costing me hundreds of dollars a year!

It is NOT my a/c - yes, I get 22mpg when I run the a/c - but the a/c is disconnected to take it out of the equation. I also lose no power in the cold.

My o2 (Oxygen) sensor is disconnected. It is bad (Engine light is on) but it is fused into the exhaust and I can't extract it.

One mechanic said without an o2 sensor my computer is not able to determine how much gas to squirt in the injectors. So why would it squirt 25% more in the cold?

This same mechanic suggested cutting a new hole in the exhaust and putting a new o2 sensor in.

Malibu - Engines - Lights - Chevrolet :: 2008 - Check Engine Light Came On?

My 2008 Malibu service manual states that the check engine light should briefly come on when I start my engine. When the engine is cold this does not happen. Also, it happens infrequently when the engine is warm. My Chevrolet dealer says this is normal as the light checks out when tested. Chevrolet has not given me a difinitive answer on this. My concern is that if this is a problem it may surface at another time when the light should go on and cause damage if not attended to. If the manual says the check engine light should go on when the engine is started and it doesn't, doesn't this mean something is wrong?

Lexus IS 2014+ :: Check Engine Light Came On Due To O2 Sensors

I was recently in an accident deemed not my fault, my 250 was in perfect condition otherwise. After the accident when I received my car from the shop, they gave it back to me with the check engine light on and told me it was my O2 sensors. I ran a scan on them and the Bank 1 has low voltage, Bank 2 has high. What could be a cause of both of them to have voltage problems? The mechanics refused to believe the accident had anything to do with it, which is complete BS. I got hit on my passenger side, 11K in damage.

Mazda - Tribute :: O2 Sensors Causing Check Engine Light To Come On

I have a 2001 Mazda Tribute with 141,000 miles. Recently, I've burned up both O2 sensors causing the check engine light to come on. My mechanic has replaced each and they've burned out again. The head gasket was replaced after that, to no avail. The check engine light continues to come on after being cleared in the computer. I have also noticed that on humid days, the car misfires on at least one cylinder., but any other time, it seems fine. What to check next? My mechanic is at a loss.

Engines - Honda - Lights - Accord :: 2001 - Check Engine Light Blinks And No Power

The check engine light will pop on an off rapid fire and the car will shake violently when you put it into drive or reverse for a minute, then the light goes off and its fine. then you'll be driving fine, and the light blinks on and off rapid fire again, and even if you have your foot to the floor, you cant get much power, then it kicks in and lurches into being fine again. I tried "tune up in a bottle" and it seems worse. I'm scared its transmission or something.. I took it and had it put on the diagnostic machine at autozone and they said there were no codes, which I find hard to believe since my check engine light is blinking on and off so much now. There doesn't seem to be any rhyme or reason to when it happens and when its fine. it will be fine for hours of driving, then in a small period of time, it will go through a whole bunch of spells of this happening.also: when this happens, the light that shows what gear you are in on the dash board goes black, then goes back on again when the check engine light goes off. What is going on with my car????!!!!!!

I have recently had about $1620 worth of work done on my 2000 4Runner because the check engine light came on and the code was P0420.. My invoice says they replaced the exhaust pipe assembly. Now 2 weeks later the light is back on with the same code...are the 02 sensors part of the "exhaust pipe assembly" or are they now going to tell me I need a bunch (2-4) 02 sensors replaced.

Engines - Lights - Jetta - Volkswagen :: 2003 - Flashing Check Engine Light / Burning Plastic Smell

Last night I was driving in my 2003 jetta on the intersate at 65mph with the cruise control on. As I came into a turn I had to tap the brakes. As soon as I did the check engine light came on. The car was doing fine so I drove home from school. Today I drove the car to work which is a five minute drive, and back with no problem. I later went to grab lunch and bring it home and then I noticed the check engine light started flashing. I then felt the engine start to stutter, as if it was misfiring. We had the windshield defrost when we started to smell a rotten egg smell. Luckily we were pulling into our drive when we smelled the odor. I immediately turned off the car and got out. I couldn't smell the rotten egg smell, but I did smell burning plastic. I didn't see any smoke and could not pinpoint the cause of the smell.

Mazda - Protege :: 1992 - Check Engine Light Coming On - Rough And Sputter

I drive a 1992 Mazda Protege. Recently had an oil change and put in new air filter. Recently the check engine light has been coming on. Sometimes it will run rough and sputter a bit when the light flips on and then runs normal after the light flips off, sometimes it seems to run fine when the light comes on, but the light does go off and the car runs fine after it has been running for a few minutes. Shortly before I had my air filter and oil changed I did have an incident at a stop light where the car died and did not restart for a full five minutes, at which point it sputtered for a bit and then got me home.

I took into the local mazda service center and dealer (they were the only ones who had the right kind of connector to pull the error of a car this old), and they said the only code coming up was a p69 which indicated a bad thermoswitch. I have already paid for it but the parts won't be in until Saturday. I have until then to cancel the repair and just pay restock and the original diagnostic fees. Should I go through with this repair, or do the symptoms described indicate something else?

Subaru - B9-tribeca :: Check Engine And ABS Light Came On Along With Cruise Light Flashing

I've got a 2006 B9 with about 64,000 miles. Just a bit ago my check engine and ABS light came on, along with my cruise light flashing.

After researching a little bit on the forums and couldn't find an answer, I took it into the dealer, to which I was told that there was a bad oil pressure sensor for the right-hand side of the motor. I had them replace it out, and less than 20 miles down the road, the same lights appeared on my instrument cluster, and I took it back to the dealer. They informed me that there was now a bad sensor on the left hand side that would be another $380. I scheduled an appointment for later next week, and had them reset the error.

On the same day, about 2 hours later the lights reappeared on my dash, and I took the car over to a local parts store, where I used their scanner and the car now spit the following errors:

Camshaft position actuator A - Bank 1 timing over advan.

Camshaft position actuator A - Bank 2 timing over advan

Cam/crankshaft pos. correlation sensor A - Bank 2

Cam/crankshaft pos. Correlation sensor A - Bank 1

Camshaft position actuator A bank 1 timing over - advan

Camshaft position adctuator A bank 2 timing over -advan

Cam/crankshaft pos correlation sensor A - bank 1

I reset the codes, and waited another day for the lights to reappear on the dash. Again, I rescanned the errors, and found the same top 5 codes that I listed above.

Is there something more major going on here with the computer?

Subaru - Legacy :: Check Engine Light Turning On And Cruise Control Light Flashing

Had an issue with "check" engine light turning on and "cruise" control light flashing, intermittently. Dealer said we had dirty oil contaminating some solenoid valves in the system but we had just done an oil change and do so every 3-5K (car has 170K). They recommended switching around the sensors and doing an "oil flush" with another oil change. The warning light problem hasn't recurred, in the past month, since we started giving the gas cap a few extra turns after a fill-up. We're getting ready to buy a new car and don't want to give what might be a serious problem over to the next owner.

Subaru - Forester :: 2007 - Cruise Light Is Flashing And Check Engine Light Is Solid

I have a 2007 L.L. Bean Edition Forester. The cruise light is flashing and check engine light is solid. I am well into my retirement age and nearest dealer is about 2 hours away. Is this something that local mechanic can fix? He is very good, but not Subaru schooled. I'm afraid to drive it now.

Subaru - Legacy :: Check Engine Light On And Off On 2001 GT

I bought my Subaru in 2004 with 14,000 miles on it. The check engine light began coming on soon thereafter. The Subaru dealer has replaced my catalytic converter (the so-called problem) -- 3 TIMES up to 85,000 miles. The check engine has continued to come on and it goes off since then. Mostly, it's on, but now and then, it goes off. I bought my own diagnostics kit because I got tired of taking it in every time the light came on. I'm told it's the usual problems plus they usually have me get the oxygen sensor repaired. I've also been told to make sure my gas cap is tightly closed. Still the check engine light continues to come on and now and then it goes off (it's currently "on").

Subaru - Forester :: 2002 - Check Engine Light Is On?

Engine light came on two weeks ago. Had the code read at Advance Auto Parts. Code = P0420. The only performance issue was that it stalled when I started it the other day for the first time since I bought it last fall. Are there any other clues to tell what it could mean (catalytic converter vs. 02 sensor vs. anything else)? Is it really worth trying some kind of catalytic converter cleaner product?
