Question about 2008 GMC Yukon

1 Answer

What do codes B2AAA and B2A00 mean?

I can not find these codes, could they be pulling due to the code P0121 also coming up? Also what is the best option to start with on the P0121 code to fix it? I have been told by some to clean the throttle body and others to replace the sensor.

This is a rheostat. It wears out. You should replace the TPS.

Have you check the injector relay or maybe a fuse for injectors.

SOURCE: Check engine light is on and high idle (1500rpm)

Some times the E.G.R. will stick half open. This will make the engine surge or have high idle. Try replaceing the E.G.R. located under the upper intake. Do not go with after market E.G.R. The spring in them are to powrefil and the E.G.R. wil not open. Also try replaceing the O2 sensors. This could give the engine more fuel thus a higher idle. Some vehicles the T.P.S. can be ajusted, do some checking to see if yours is adjustable.

Please contact me if your problem presists.
Thanks, Charlie

See or call your local auto parts store such as AutoZone or O'Reillys for the trouble code definition. Also, make sure your gas cap is really secure, and I mean tight.

SOURCE: Code P0121 on 2006 GMC

Classic signs of idle air control not able to cope with sudden engine loads. Cleaning should resolve this. Remove ducting from air cleaner to throttle entrance. Spray with carb. choke cleaner or WD40 spray and wipe back to the alloy finish. clean the the throttle plate and push the throttle open with your fingers and clean in behind as best you can. Clean the passageways to the idle air control valve. Remove the valve and give it a thorough clean up. Reassemble and it should all be good.

You never replace anything, on a Wishing,Hoping,Pushing,Poking,diagnostic approach

You learn the vehicles Systems,Test,then Replace,if you have a failed component.

Work on the Misfire Issues.
Then you lean O2 Codes will go away.

Not a the plugs.

Think lean---Vacuum leaks,EGR Valve leak,EVAP System leaks,anything with a hose that lets air into the intake system.
Exhaust System leaks,near sensors

What can cause the check engine light to be on?


Circuit Range Performance error.

When is the code detected? Malfunction is detected when an excessively low or high voltage from the sensor is sent to ECM. Possible symptoms Engine Light ON (or Service Engine Soon Warning Light) P0121 CHEVROLET Description The throttle position sensor (TPS) responds to the accelerator pedal movement. This sensor is a kind of potentiometer which transforms the throttle position into output voltage, and emits the voltage signal to the Engine Control Module (ECM). In addition, the sensor detects the opening and closing speed of the throttle valve and feeds the voltage signal to the ECM. Idle position of the throttle valve is determined by the ECM receiving the signal from the throttle position sensor. This sensor controls engine operation such as fuel cut. On the other hand, the Wide open and closed throttle position switch, which is built into the throttle position sensor unit, is not used for engine control.

Whats mean the code B2AAA for 2009 Mini cooper s Thansk


it means this P0420, make appointment for service, should come out like this code but if you out of service do this remove BCM (Body control module), PCM, ECM tcm FUSEs, waited 30 mins, the reconnect them and put battery back on, or if you don't want to do that take the battery off, then go inside the car and turn the ignition on and the lights and anything ells you can turn on. they won't work but they will drain the voltage stored in them, leave like this for 15-40 min and then reconnect the battery should be back to normal. but turn every thing off again before putting the battery back on.

I had a code P0121. I bought the sensor and had it replaced, now the code still won't clear. I need an inspection ASAP but the check engine light is still on.


I should start by saying a trouble code does not mean a component must be replaced. It only means the signal from the sensor is out of range or the affected circuit needs to be checked out.
Code 121 means the signal from the TPS is either out of range or not where the computer thinks it should be. Such as the TPS tells the computer the throttle is closed when it is actually open.
You would need to use a scanner to see the data coming from the sensor to tell if it is working or not. The problem could be the throttle or the wiring back to the computer.

P0322,P1544,P0121


The fault code P0322 means "Ignition/Distributor Engine Speed Input Circuit No Signal"
The P1544 means "Seat Direction Switch Assembly Circuit Open"
The P0121 means "Throttle/Pedal Position Sensor/Switch A Circuit Range/Performance Problem"
when you know the code, you can most likely repair it yourself.

What does the service code B2AAA mean?


You must have a code reader that is CAN enabled. CTSs as early as '04 require a CAN enabled reader. the 06 cts uses a CAN OBD-II CODE READER/EOBD SCANNER. When buying the scan or code reader for your vehicle, make sure it supports the Controller Area Network (CAN) protocol. CALL THE DEALER OR AUTO-ZONE MAY BE ABLE TO TELL YOU THE PROPER NAMED SCANNER TO USE. GOOD-DAY !

My check engine light is on. The code is P0121


I believe all the Mopar OBDC codes are the same. A list of the 2001 codes were posted on a PT Cruiser site here: 2001 Chrysler codes

Your error says the throttle position sensor and MAP sensor disagree with each other
