Santa FE SM (2001-06) :: CEL P2138 Code - Engine Lost Almost All Power
Dec 5, 2012
Check engine light came on and stayed on today. Engine lost almost all power so I guess I was in "limp home mode". CEL ODB-II code was P2138 according to AutoZone.
Accelerator position sensor malfunction
Probable causes:
1. Open or short circuit condition
2. Poor electrical connection
3. Failed APS.
After turning off the vehicle, it seems fine at least in town but the check engine light is still on. This is the first "problem" with the vehicle and it's at about 98K.

Driving along, suddenly lost gears, engine revved a slight bit then lost power and stalled, the engine turns over but will not start but when it turns its in a lower key sound, the timing belt is in place but has recently been changed, would you think it has slipped? Seems a total lack of combustion in the top of the engine, would a slipped timing belt cause this?

I was headed down the highway in my 2007 Santa Fe last night. All of the sudden, I lost engine power. I pushed the gas peddle and nothing. We coasted down to a stop on the side of the road. I attempted to restart, all it did was turn over. I noticed the OIL light was on, so I got out and double checked my oil level. Right up to the full mark. Probably about a year ago, I had a check - engine light. I have a code that indicates that my gas level sender has failed, so my gas gauge does not work. I am sure you are saying.....he just ran out of gas. Well, not the case. I filled up the day before, and figured I had another 100 miles left on this tank.
Over 171000 miles on it and I have no intention of giving it up soon.

The light engine is on - I understand that the O2 sensor on bank one is gone, the car hesitates and I would like to understand what is wrong. Maybe other sensors or perhaps the turbo. The car has 62,000 miles. Will the car recup power by replacing the bad O2 sensor?

I have a 2001 prius jap import. On a trip it beeped and up came the triangle, check engine light and car with !. The car lost all power and the engine stalled when I pulled over. I plugged in my obd2 scanner and no codes except 3000. Took it to our local toyota dealer who confirmed that code. Had the battery swapped out and still it does the same except now no codes. The car has below normal pickup speed and I can hear the engine rev a little but it does not seem to make any difference. Seems all the power comes from the battery. It will stall when all the error lights come on.

My friend's Jetta was running fine. One day about to drive out of the driveway it started doing 2 things:
1. Felt like it lost power braking, just stopping by manual effort by pushing down pedal hard.
2. Engine stalling unless you keep the gas pedal depressed and holding the engine to about 3,000.
Car currently sidelined until this is fixed... Having the brakes go like that at the same time is strange so where to start. Brake fluid level is fine.

I have an 2004 Santa Fe and im having some Mass Air Flow Sensor problems but I dont know what's wrong. My engine light came on for the second time after awhile. And I got it checked for the code and of course it was my sensor again. The first time I just giggled it around and the light went off. I did the same thing today with giggling it again went off. So I feel like it might be a loose connection but I really hope it isn't failing because im pretty sure that's uber expensive to fix.

So the check engine sign came up on my car and using the OBD it tells me the error is P0113. After googling the information, it looks like I have an issue with IAT sensor.
I opened the air filter and what I believe what could be the sensor and there was nothing clogging up, so I'm assuming the sensor needs to be replaced
Question is where is the IAT sensor located and how do I dis-assemble it so I can replace it. Is it the piece that is located just before the air filter?

I just joined the forum mainly to care of my dads 2001 Hyundai Santa Fe but also I got a check engine light on my way home from work last night.
From last night I saw that oil was all over the timing belt. Today I inspected it with a Coworker and his OBD II reader.
Error Code was P0455, EVAP - Evaporative Emission Control System Leak Detected (gross leak).
Now the oil leak is stronger since the oil spills is on hood (inside hood). I will make a picture tonight when I get home.
I personal think it's leaking from a tube/ valve on top of the timing belt (picture will show more tonight). Thinking of cleaning the timing belt area, then drive a little around or leave it in idle to spot where the leak is from.
Common issue? I googled around but since P0455 is a common issue (on my 9-2x as well) I couldn't find anything about this I am also limited from my search since I am currently at my work PC incl. strong firewall.
I will see if google let me find a picture...

Trying to get my daughters Santa Fe going. Engine stalling. Idles very slow. 2001 model with 2.4 engine, auto trans.
Code P0102 is active. Cleared with scan tool and it comes right back.
Replaced the MAF and no change.
Checked the intake for leaks / vacuum leaks and none found.
Checked for debris up-stream from MAF and all is clear.
Air filter is clean and dry.
Checked harness plug and found the pin 5 has 4.6 volts on it from PCM. This is the signal wire from MAF to PCM. 4.6 volts is KOEO.
IS THIS NORMAL OR IS PCM BAD ??? All other pins / voltages on harness plug are normal.

I have a 2005 Santa Fe with the 3.5 with 112000 miles on it. I had the engine light come on with the code P0302 cyl #2 misfire, I got spark plugs, plug wires to do a tune up on it. I changed all of it and got it back together, started it up and it still had a miss to it. I then took the front spark plugs out and did a compression test on it. #2 was at 85, #4 was at 120, and #6 was at 160. I couldn't check the back cyls because I had already put the intake back on. I then did a wet test, and all the cyls came up to 160. So this tell me that the piston rings are bad in #2 and going bad in #4. I have kept all the oil changes up and up to this point I haven't had any trouble with it. Having this problem with there 3.5?

My engine doesn't run smoothly (like a misfire) when accelerating at hwy speeds, especially when the outside temp is above 20 degrees... the warmer the temps are, the worse it is.
I have a code P0431 - "warm up cat efficiency below threshold (Bank 2)"
Is it an O2 sensor problem, and if so, which one is it and what is the Hyundai p/n for the sensor? Bank 2 is in the front, correct?

2004 2.4L Hyundai Santa Fe here, died whilst travelling, lost all power and then wouldn't start. Sounds like its trying to turn over.
The fuel cut off seems to have been activated as it clicked when I pushed it but the car still wont start.
I do not have any engine management lights but when connecting the code reader I got P0320, however the code was stored but not present... and still the car will not start. I cleared the code and the code didn't re appear but the car will still not start.
As the code isn't immediately present does this mean the sensor is at fault or do I have other problems?

When I bought the car a few weeks ago, there was a p0507 code for a high idle in park, about 1300 RPM, but sometimes shooting up to 3000 when I shifted into park and then dying down. The code goes on and off intermittently. Not that big of a deal at first. Then I started noticing that if I revved it in park it would take forever to die down to 1300, and sometimes would fluctuate around 2000. I also noticed hesitation while accelerating around 1500 RPM and the transmission hunting for gears while accelerating, as well. I noticed my throttle cable was very slack so I tightened that, and bought myself a throttle position sensor, thinking that might be the problem, but didn't install it yet.
I was driving on the freeway yesterday in cruise control and then I started losing power while my foot was on the gas. With my foot on the gas, the throttle would cut out every second. I was basically one second of throttle, one second of no throttle, all the way down the highway. Almost impossible to drive. This continued even after I turned cruise control off. I limped my way to Home Depot and installed my TPS in the parking lot, and drove most of the way home with no issues, although I still noticed a slight hesitation while accelerating. Alas, I tested cruise control again and then the throttle on/off problem started again, then I could barely drive the thing, even after cruise control was off again. I'll be returning the new TPS to Autozone today, since apparently that's not the problem. What's my next move?

2005 3.5L FWD. 5 days ago I left the house, the engine was running smooth at idle but having hiccups when accelerating. Check engine light went on when accelerating but going off at idle. Turned around at the first stop light, parked the car home and pulled code P0302 misfire on #2 . Figured it's most likely the coil, was going to order one next day but to my surprise, no more check engine light next day and engine has been running smooth since then. Probably drove 100 miles since with no issues. I have 6 spark plugs waiting to be replaced but it's too cold to do it right now unless it's an emergency. Car has 105k miles now, spark plugs were changed at 63k. Was this just a fluke and P0302 will probably not come back or should I not risk it and just go ahead and replace the coil? If I end up replacing the coil, should I do one coil or all three?

I have a 2001 santafe with a 4 cyl The code 102 was up so I replaced the mass air flow censer . I go on a test drive and the light stays off , but when I go to re start it again the light come on and stays on, with the same code. The only strange thing is the idle will raise for a min then drop down to almost a stall.

I got an Error Code of U0D00. What this is or means. The scan tool says to refer to your manual but I don't have one.
What the vehicle is doing is that it will work fine for a while then when you stop (in park) the engine will rev really high and back down all by it self for example. It will go up to 3.5 and back to 1 rpm repeated. Then when you start moving the car it will continue to idle higher like you are pressing the gas. During all of this the check engine light will appear?
