Chevy Engine Codes (OBD-II scan)

this may be something to sticky someplace...

When retrieving Chevy trouble codes with an OBD II scan tool, proceed as follows:

1. Connect scan tool to the 16-pin data link connector (DLC) located underneath the steering column. The connector may have a removable cover.

2. Turn the ignition on.

3. Follow scan tool manufacturer’s operating instructions to access the Diagnostic Trouble Codes (DTC's).
Remember, these are manufacturer specific codes only. Refer to our Generic OBD II code list for definitions on all other Chevy diagnostic trouble codes.

Good info, I vote for the sticky.

I'll put it up so i dont have to look for it..

P0340 Camshaft position sensor malfunction

Would be better if it had them all

How about p2106, p2110 and 2101

I have P2135....

P2135 Pedal Position Switch A/B Voltage Connection error

The code P2096, post catalyst fuel trim system too lean on bank 1 simply translates to a lean (too much air and not enough fuel) condition the PCM recognized through the signals from the oxygen sensors. Bank 1 has no meaning on a four or straight six cylinder engine with a single exhaust. On a V-6 or V-8 engine it refers to the oxygen sensor on the number one cylinder side of the engine as bank 1.

thanks for the reply
my mechanic said it was the oxygen sensor and also the flex pipe was rotted out

Hello ,

I have a P2076 engine code... what should I look for ?

Thanks !
