Error codes P0430, B211B, C1279, C1517 and C2769

Hi,

The P0430 is the bank two catalytic converter. A partially plugged converter can cause drivability issues such as a loss of power. The other codes you listed are all related to the stability control system. I noted that you indicated little knowledge, but to determine the cause of the faults, diagnostics need to be followed. Take a look through these diagnostics and the attached pics and let me know if it is something you feel comfortable doing.

Refer to Vehicle/Diagrams, Vehicle Dynamic Systems for schematic and connector information.

Normal Operation
The accelerometer (lateral and longitudinal) and the yaw rate sensor are contained in the stability control sensor cluster. The sensor cluster measures the vehicle acceleration and yaw rate, then sends the signal along a dedicated high speed controller area network (DHS-CAN) bus to the anti-lock brake system (ABS) module, circuits VCA23 (BU/WH) and VCA24 (GN/OG). Fused battery voltage is supplied to smart junction box (SJB) fuse 35 (10A) from battery junction box (BJB) fuse 53 (30A) along circuit CBB53 (GY/BN). This voltage is sent from SJB fuse 35 (10A) to the sensor cluster along circuit CBP35 (YE/GY). Ground is provided through circuit GD151 (BK/GN).

Possible Causes
Circuit open
Circuit shorted
Stability control sensor cluster

Let me know. I realize it is somewhat confusing if you are not comfortable, but I can try to help from here.

Take care,

Hi,

I have a feeling the bank 2 catalytic converter is either partially plugged or is loose inside and causing a temporary blockage in the exhaust.

Try this. Remove the upstream O2 sensor for bank two and see if the problem changes or take a rubber mallet and tap on and around that converter to see if something sounds loose in it.

Since you are hearing that sound, it could be something causing the blockage, and the P0340 is related to the bank 2 catalytic converter. Does the sound you mentioned sound as though it could be exhaust being restricted?

The good news is that bank 2 is closest to the radiator. I attached a pic below showing both bank 1 and bank 2.

Let me know what you find.

Joe
