Toyota - Camry :: Code P0171 - Lean Bank 1 Sensor 1

I have a P0171 code (lean bank 1 sensor 1) on my 2002 toyota camry 4 cylinder. I don't have any other codes except for an unrelated P1780 neutral safety switch code. It has had both codes for over a year.

I have replaced the fuel filter, the upstream o2 sensor, and the PCV valve. I also cleaned the MAF sensor. The mechanic performed a smoke test and found no vacuum leaks. Did a fuel pressure test and it's normal. Mechanic thought it would be fuel pressure because the car starts a bit slow when cold, but nope. The car runs great and still gets great gas mileage. I've never experienced a misfire in my 12 years of owning the car. I am asking because I am at a loss as to what it could be.

Toyota - Camry :: Heated O2 Sensor Bank 1 Sensor 2 Is Failing

I just had an OBD code pulled on my 2010 Camry and it turns out that my Heated O2 sensor for Bank 1 Sensor 2 is failing. I'd rather do this myself if I can but I can't figure out where this thing is. Is this something I can access myself and swap out? Or does this need to be fixed by a mechanic?

Ford Super Duty (1999-2016) :: Code P2195 (Bank 1 Sensor 1 O2 Sensor Stuck Lean)

So I just replace my Cat. Converter with all new sensors in them. I just replaced my spark plugs. (I'm knocking out these check engine light problems) and I think I'm getting close to the root as to why these other parts went bad. Why my o2 sensor would be stuck on "lean" ....

Ford F-150 - 1997-2003 :: 2000 - P0136 (Bank1 Sensor 2) Code

I recently replaced both the downstream O2 Sensors in my 2000 4.2L F150 because I was getting a P0136 (Bank1 Sensor 2) code that I couldn't get rid of by cleaning the connector or fixing wires. 110K miles. Calif truck. No other codes and has always passed smog test easily.

When I pulled the sensors, the Driver's side unit was extremely sooty, as compared to the passenger side (bank 1). The code failure was on bank 1.

Is this normal or is there some rich condition on the driver's side bank that I need to check into ? Originals were Bosch, replaced w/ Motorcraft, if that makes any diff. One on left is driver's side unit.

Ford Escape / Hybrid :: 2004 XLT - CEL Popped Up For P0136 / O2 Sensor Code

2004 XLT 3.0L 141K

I just bought the truck on Monday, the CEL popped up on Tues. It shows code 0136. No other codes. CAT "not ready" on scan tool

A google search proved this is a common topic that for some owners is a repeating and cronic sort of issue. What I've read online is that there is an assortment of things that can cause this O2 sensor to throw this code:

Actual bad O2 sensor
Faulty wiring or connection
Misfire throwing mix off
bad convertor

I don't believe this list covers all the accounts I read but these I have were definitely repeat offenders. My intention is to take to a dealer and let them have first crack at sorting it out. I'm handy enough but I see this as something where an unseen detail can drive ya crazy.

Camry :: 2006 - Getting Code P0136?

My 2006 Camry V6 had the code P0420 before. I replaced 2 downstream O2. Now it throws code P0136. What should the next step I am looking for here? Is it a CAT issue?

If I need to replace CAT, do they have custom (modify) CAT to improve the performance?

Corolla / Matrix 2009-13 :: 2010 Does Code P0037 Is For Bank 1 Sensor 2 Oxygen Sensor?

I have a 2010 Toyota Corolla 1.8L, the base model.

I recently had a check engine light, VSC off light (blinking) and traction control light come on. I took it to Autozone and had a p0037 code ring up for a new Bank 1 Sensor 2 oxygen sensor (downstream). I believe I have found the correct sensor (located under car, approximately near drivers seat) and it looks simple to replace, aside from the fact that the wires go through the car body.

Can confirm that I have located the correct sensor? And if so, what is the best way to get to where the wires connect?

Is it located under the drivers seat? What should I do about the rubber grommet located under the car where the wires appear to pass through?

Ford Ranger / B-Series :: 1999 - P0135 O2 Sensor Heater Circuit (Bank 1 Sensor 1)

1999 Ranger 4x4 4.0 - P0135 O2 Sensor Heater Circuit (Bank 1 Sensor 1)

I have replaced the 02 Sensor, Passenger Side (Pre-Cat), with a Motorcraft DY831...

I reset the Check Engine fault codes, and took it out for a 50 mile journey... Check Engine light is back on, with the same exact code... What next?

I understand that it may be a fuse, and/or it may be a short in the wiring... Exactly how to test the wiring from the connector at the 02 Sensor all the way back to wherever I need to test?

I really need detailed directions, like wire colors, voltage required, or ohms, or whatever is included in this process...

Jetta - Volkswagen :: 2006 - CEL Code P0332 / Knock Sensor 2 In Bank 2 Faulty

I have a 2006 VW Jetta with 92K miles and just a couple of days ago my check engine late came on and when i took to an auto store to check the code, it came as P0332, Knock sensor 2 in bank 2 is faulty. Three things have happened all around the same time and I am not sure if they are related and are just coincidence.1.Check engine light came on.2. I have noticed after that, my car RPM has dropped, idles at about 600-700RPM and when trying to accelerate, it tops at 3000 RPM and feels like the motor cuts off at that point and I have to step off the gas and the car runs ok again, but cant go over 3000.

Had trouble getting on the interstate due to this and thought the car was going to stall, but it didn't. just had to back off the gas and let it run, It did go up to the speed that I wanted, but seems like it wont go past the 3000 RPM point.3. My fuel gauge, drops to empty when it reaches the half way mark on the meter. It stays at the correct level when I start and keep the car in idle, but when I start moving, it drops to empty. When I fill up the tank, it goes all the way to F, and after the car goes the usually of about 190-210 miles, when It reaches the half full level, the meter drops to zero, so have been using my trip odometer to drive after that.
