The car has more than one O2 sensor. This code is for Bank 1 sensor 1, on the exhaust manifold.

Mass Air Flow sensor! Just remove your air filter cover. Go to Auto Zone and purchase some solvent. Spray past the air filter and it should correct the problem. If not, replace the Mass air-flow sensor. This is commonly mistaken for an oxygen sensor. Mine did this and I followed these steps and it fixed the light. BTW, the light stayed on for 5 years before I fixed it. Never hurt anything. It's normally something to do with emissions. Dummy lights. :)

SOURCE: i have a p1135 code

Code P1135 is a vehicle specific code for selected Toyota vehicles - it really helps to know what car you are working on...Year, Make, Model, Engine Size, Automatic or Manual Transmission, etc. There may be Technical Service Bulletins that apply to your vehicle that cover things like reprogramming the engine controller to correct this code, etc. Nobody can give you that information if they don't know what kind of vehicle we are talking about.

In general, the code description for code P1135 is "Air Fuel Ratio Sensor Circuit (California Emissions )"
The possible causes are
1. Open or shorted Air Fuel Ratio Sensor (AF) circuit
2. Faulty AF sensor
3 AF sensor heater or heater circuit shorted or open
4. Engine Control Module (ECM) Fault

The Mass Airflow Sensor (MAF) cannot cause this code - this is a "CIRCUIT" code, not a not a "LEAN" or "RICH" Oxygen Sensor (or AF Sensor) code. The MAF can only cause lean or rich codes.

Most of the time, this code is caused by the sensor itself, however, as I mentioned earlier, there are Technical Service Bulletins for several Toyotas that involve reprogramming of the Engine Computer.

What does code #P0171 mean for a 96 Villager?


"System too lean (bank1)" O2 sensor is giving this error code. There are two O2 sensors one near the engine and one downstream. It could just be an anomaly or the sensor could be going bad. (Bank 1) is the O2 sensor closest to the engine. I had a PT cruiser that constantly gave this code even after replacing both sensors. If the car seems to run fine, clear the code and see if it reappears immediately. If it does then the O2 sensor is probably bad. If it doesn't come back then it was probably an anomaly. I would get this code every 2 or three months on the PT cruiser and would just clear the code to turn the check engine light off as the car ran fine.

COULD HAVE SHORT IN WIRING CIRCUIT OR PCM PROBLEMS.IT WOULD NOT BE SAFE TO DRIVE CAR WITH O2 SENSOR FAULT. BECAUSE FUEL MIXTURE WOULD BE TOO RICH CAUSING CATALYTIC CONVERTER DAMAGE CAUSING IT TO OVERHEAT GET RED HOT UNDER CAR CAUSE FIRE AND YOU WOULD HAVE A LOT OF FUEL CONSUMPTION .I WOULD NOT DRIVE CAR.BETTER TO USE A RENTAL CAR FOR LONG TRIP GET CAR CHECK OUT AGAIN AT THE DEALERSHIP.

I have a 97 wrangler 2.5. Check engine light is on, running lean, loss of power and high fuel consumption. I have replaced the o2 sensors, reset check engine code. light stays off and engine runs great for...


Something odd about what you posted. An engine that is running lean shouldn't be using a lot of fuel. Lean is when there isn't enough fuel going into the engine. Two other sensors that regulate fuel flow are the map sensor and throttle position sensor. Temp sensor generally would cause a rich condition but I'd test that too. Be sure to check for vacuum leaks at the manifold and lines as well as fittings... A vacuum leak will give the O2 sensor a lean reading...seeing that, the computer will try to compensate by adding fuel. Clearing codes can change the way it's running but as soon as the computer runs through it's internal diagnostics it will turn the light back on if there is a problem.

Check engine light on; Gas milage went from 19 to 15, emission ba


YES!!, you had it tuned, it runs good, but gas mileage dropped, and check engine light is on,it sounds like the o2 sensors are slow or even dead, i would replace them for sure and that just might solve all your problems,good luck, hope this helps.

Possible Causes
The following are malfunctions that could cause a rich condition:
^ Fuel pressure too high. Perform fuel pressure test.
^ Leaking fuel injector(s). - Perform pressure leak down test.
^ Vacuum leak around the MAP sensor grommet.
^ Oxygen sensor contamination.
^ Restricted exhaust or air intake.
^ Fuel Vapor Canister saturated with fuel.

IMPORTANT:
If the front oxygen reading voltage is above 600 mV and the rear HO2S is above 600 mV all the time, the O2 sensors are probably not
at fault.

Replaced o2 sensosor, SES light back on


If he used a "universal" O2 sensor, you could have a wiring problem. I had the exact same behavior on a Mazda MPV. The universal O2 sensors have to be crimped to the old sensor connector, which can cause problems. You can check the wiring closely, or insist that he use an OEM sensor, which will have the proper connector attached.

1996 olds achieva check engine light remains on. Already replaced both oxygen censors and catalytic converter but the light remains on. Scan tool was placed on the o2 censors but it show "no activity".


What were the codes??? 
Try this, turn the ignition key to the on position and pull the ECM fuse out for 10 seconds, then place it back in and start the car.
The car may stall and let it, just restart it the second time and things should be fine. It's just the ECM leaning the Engine and Transmission. 
The check engine light should be off and go for a test drive. If there is a problem the check engine light will go back on after you travel over i believe 5 MPH.

Check Engine Light


It sounds like you may have a failing Mass Air Flow sensor, seems like Ive been seeing these tied together quite often. Its a little tricky but a good repair shop should be able to test this sensor. I dont want to tell you to replace it without having it tested cause they are a bit pricey but check around, you never know. Hope this give youu another idea where to look.
