Take the car to an AutoZone IF it's driveable, ask for the free check on "alarms" and they can set it up to reset.

Replace the Oxygen sensor. All your trouble codes are downstream of the oxygen sensor, and are related to it.

Once you replace the oxygen sensor (replace with a BOSCH sensor!), remove the positive battery cable, step on your brakes for 10 seconds, then reattach the cable. This will clear the codes from your ECM (Electronic Control Module).

SOURCE: My 1995 525i has fault code 12210 O2 sensor

if the 02 sensor is unplugged and you are reading a scan tool from the diagnostic link then of course the 02 reading is wrong
if you are using a volt meter right at the connector thats on the sensor then the 02 will read lean because the heating elements in it are disconnected when you unplug it
check 02 voltage with engine warmed up and 02 sensor connected you will have to pierce insulation with your probe

Check for intake leaks, intake hose leaks, check mass air flow sensor.
02 sensors will keep setting off a lean code until the air problem is fixed.

It's an o2 sensor code. So you more than likley have burnt wires associated with that o2 sensor.
P1133 = O2 Sensor Fault - Insufficient activity (Bank 1 , Sensor 1)You remove the negative battery connection from the negative battery terminal for 10 minutes.

You ALWAYS reset your computer when you do sensor swaps, when fixed erase code, and see if it stays out. your pcm is getting the wrong info from sensor. good-day !

I have 3 codes from my scaner p2111 p2112 p2238


P2111 - Throttle Actuator Control System Stuck Open.
P2112 - Throttle Actuator Control System Stuck Closed.
P2238 - O2 Sensor Positive Current Control Circuit Low Bank 1 Sensor 1



For the P2111 & P2112 you will need to replace the throttle body this can be pricey since the TAC is built into it. Try cleaning it good and see what happens. This can also trigger the P2238 code if its dumping fuel.
For the P2238 check the connections on the o2 sensor or replace the upstream o2 sensor that should correct it.

My Service Engine Soon light came on about a year ago. I took it into the shop and got that problem fixed but the light stayed on, so I took it to advance auto parts and code tested it and it said that...


There are several types of O2 Sensor codes. There can be "Lean O2 Sensor" codes, "Rich O2 Sensor" codes, "O2 Sensor Slow Response" codes, or "O2sensor Heater Circuit" codes. The specific code that is being set changes the way you must go about diagnosing and repairing the problem. I will say however, that in about 80% of all the O2 Sensor code problems that I have had to diagnose, the O2 Sensor itself was NOT the problem. The O2 Sensor was only reporting a problem that was actually caused elsewhere. O2 Sensors are the final checkpoint in the engine management system. I think of them like a report card. If the O2 Sensors are right, the rest of the engine management system is right. If the O2 Sensors are not right, the rest of the engine management system is probably not right. (Except in the 20% of the cases where the problem is actually being caused by a failed O2 Sensor)

I have code 406 what does it mean?


on youe veicle you have to follow procedures to check O2 sensors
voltage to high more than 3.7 volts
circuit shorted or O2 sensor is no good thats for code 138
code 171 contaminated O2 sensor
406 is your EGR system shorted open thats whats probably causing your O2 sensors to contaminated fix the EGR and clean passage way to intake

Engine light was on and engine idles rough.


these O2 sensors are cat convertor check sensors. id be checking cat convertors and hopefully you should try replacing if not all ready is the front bank 2, O2 sensor
if you have scanner can you see fuel trims in data display to confirm high fuel trim only on bank 2 either +-5 or more indicates problem and if bank 2 sensor 2 has fixed high 700mv reading cat no good(warm idling)

Obd codes for a 1994 cadillac seville sls


It means the heater circuit for the O2 sensor has failed. An O2 sensor has to be up around 900 degrees to function properly, and if its heater fails, it won't get up to temperature (thus the "not ready" diagnosis). Replacing the O2 sensor will fix your problem.
