Tacoma - Gasoline :: 2003 - Check Engine Light Returning A Code For Failed Up-stream Air / Fuel Sensor
Jun 14, 2014
My '03 Tacoma Prerunner V6 has 116K miles and recently lit up its Check Engine light, returning a code for a failed up-stream air/fuel sensor. I recently drove across country, using many different fuel formulations ranging from CA gas to midwest ethanol to whatever they put in the gas here in the NY-NJ area (a mystery ingredient that seems to turn motorists irate and confuse their horn as a turn signal.)Anyway- age, or fuel, what killed the sensor? If fuel, will it happen again by time I get back west?

Just over 6000 miles....Yesterday morning the light came on. Dealer wouldn't look at it for a week. Went to my mechanic this morning to check the code it was p0181 fuel temp sensor. I read something online about the block heater making it too warm. The other night it was cold so I plugged it in, then yesterday morning it got warm overnight like into the lower 40s. I noticed the grill felt warm too. My mechanic cleared it if it comes back on do I have an issue? Is it ok to drive?

2000 Tacoma v6 has has always ran good, but has check engine light code P300 & P306. cly 3 & cly 6 missfire, lean bank 1. Vacuum test showed no problems.
I've changed plugs & wires, switched coils around cleaned mass air flow sensor, checked timing. Ran Seafoam through intake, and gas tank. Check engine light went out for about three miles, then came back on. What else can I do to keep that blinking check engine light off?

I've been getting this error code recently ("Fuel Trim,Bank1 System too Lean"). I have a Scanguage, which let me get the error code, and I used it to reset the message - it came back about a week later. I took it to a local repair shop after the second time, but as I'd already cleared the message, he couldn't do anything. It came back about a week later, and this time I took the vehicle in as soon as the yellow light showed up (without connecting the Scanguage).
The mechanic said that he found both P0171 and P0172, and that the problem was a loose vacuum hose AND a failing Mass Airlow Sensor. They reattached the hose and cleaned the sensor, but said that the latter fix may not last - the light came back on two days later. I took it in again (this time, checking the codes, and found only P0171) and he said this confirms the problem with the sensor and he'll have to replace it ($280 for the part, plus labor, less a discount on the labor equivalent to the labor he put in to clean the sensor.)

Just picked up a Toyota certified 2010 Prius III....less than a week later, the check engine light comes on. Took it right back to the dealer...in which they said its the air/fuel sensor. Toyota warranty services was closed, so they need to check tomorrow if its covered by the remaining warranty or not.

2004 XC90 T6. Local Volvo dealer (Bangkok at the time) said my check engine light was due to the O2 sensors going bad. I changed out the one under the car, then my wife threw out (accident) the other so I didn't change the one accessible from the hood. The check engine light went away so I figured that was that.
Fast forward a year later, I buy an Autel Maxiscan MS509 and now I'm getting check engine code P0455 which is probably the O2 sensors I didn't replace. Other than deductive reasoning, is there some way to look at the data on my OBD reader to confirm which O2 sensor is bad?

I have a 2012 hyundai accent. The check engine light came on. The code read knock sensor. Before I could get it into a shop, it went off. It didn't come back for 11 months. When it did come back, the same code was read. Again, it went off the following day before it could be looked at and hasn't been seen since. The shop says that even though there is a history code, it would be hard to diagnose since it isn't an active code. I noticed absolutely no difference in performance when the code was active. Both times it went on, the car was idling for several minutes with the ac on, and it came on as i accelerated onto a highway immediately afterwards. However, it has idled like that many other times without the light coming on as well.

My friend was told by Toyota that the Air Fuel Sensor code was the reason why her 2010 Corolla VSC and engine lights were on. This was after she visited her mechanic who changed the O2 sensor.
Is there a way to change the Air fuel sensor herself without having to pay Toyota...

My 2005 Camry check engine light is on. The trouble code is P0138, bank 1 sensor 2 oxygen sensor. Engine is the 2AF-ZE. Not a California emission car. Car is Japan built. It has two O2 sensors. What is the correct OEM part #? I believe it would be a Denso?

So, I have my check engine light and the code is p0327 (knock sensor). Clear cose but it returns. Going on for 3 days now. I was suspicious that something else is going on. I also remembered I've been using a little more antifreeze in the reservoir. So, today I needed to watch the coolant. I ran the car for an hr and I found a lot. Red coolant on my belt, the back passenger side of my engine and it was caked on with coolant. I think the water pump is going up.
I was concerned that coolant was also leaking from the intake manifold but it's only the right side, so I'm pretty sure the coolant is being slung around from the belt. I rinsed the engine down and the knock sensor code went away. Temporarily, until more coolant got back there. Do you think I will need to replace the knock sensor along with the water pump or should the sensor work ok after some intense cleaning after the water pump replacement?

This issue pertains to a 2006 Camry LE 4-cyl.
My check engine light came on - code P0032 (upstream O2 sensor). I bought a new sensor from O'Reilly Auto Parts. After installing the new sensor, the car would jerk while accelerating. This continued to happen until roughly 30 miles or so when the engine light came back on and the jerking stopped! I re-scanned the car and it showed the same error - P0032. I then erased the code, and the jerking issue resumed.
I assumed this was caused by a faulty O2 sensor. I returned and got another one. Same issue.
Is this the result of not getting an OEM sensor from the dealer? Or is there something else I should be worried about?

I have a 2002 Jetta 1.8t. My check engine light came on and it gave me the code P0135 sensor heater circuit. Bank 1 Sensor 1. We bought a new 02 sensor and replaced it. We definitely bought the right one too. Cleared the codes. After a little driving the CEL came back on with the same code P0135. What is wrong and how I can fix this?

I cleaned my k&n air filter on my 02 passat 1.8 turbo let it dry oiled it very lightly, and 50 miles later I get a check engine light on, pulled the code 16486 and it says Mass or Volume Air Flow Circ Low Input. Cleared the code put a frame in until I can get it filter. Why that would throw me that code, k&n oil gumming up my sensor??

1996 Ford Explorer on a small island with no mechanics. Vehicle does less than 100 miles per year, never over 20 mph. The check engine light came on and the code reader says it's a problem with the Camshaft Position Sensor. The vehicle runs fine, just as it did before the check engine light came on. I'm tempted to put some electrical tape over the check engine light and keep driving.

I had a Check Engine Light a couple months ago, and I took the car to the garage to have it checked out. They told me they got a Fuel Pressure Sensor malfunction code, and that the sensor had to be replaced. I did so myself, an it is ridiculously easy, and the car worked fine. I noticed the Check Engine Light blinked a couple of times while I was driving, but never got steady. A couple of days ago, it did. Out of a bad gut-feeling, I purchased a ODBII scanner, and I scanned the car myself. I got the same error code as the garage did, but the sensor should be fine.

We have a 2003 Passat 1.8t. Had the Check engine Light come on. Went down to AutoZone and hookeded up the OBDII reader. Came up with P0171, Fuel System for Bank 1 was too lean. Probable causes:
1. Fuel Pressure of MAF (If Bank 1 & Bank 2 set codes together)
2. O2 Sensor
3. Ignition Misfire
4. Fuel Injector Problem
Car has 60K - has always run well. Wife says she thinks it's running a bit sluggish. I rarely drive the car, but I think she's right. Car is not missing or running rough.
I cleared the code & started the engine; Check Engine Light is off; then looked at the codes and I find a P0171 (Pending). She tells me that the light has been on before & then gone away. So I guess it clears itself, but eventually comes back.

When I bought my 2003 20th it was completely stock, except for a pos blow off valve had been installed, and get this, the diverter valve was left on, and just capped off. I installed a no name CAI, and the check engine light came on, i had it turned off and when i start the car, or rev the engine high at all, triggers again.
