P0202 GMC - Acadia

Question

Out of the blue my 2007 GMC Acadia stated running rough, the check engine light, service stabilitrack, and service traction control came on. I hooked up the computer and it's throwing all kinds of codes. P0202, P0404, P0606, P0017. Which should I investigate first?

Answer 1

P0202 Injector control circuit cylinder 2

P0404 Exhaust gas recirculation circuit range perfromance

P0606 Control module internal performance

P0017 Crankshaft position (CKP) exhast camshaft position (CMP) correlation

Clear the code and retest the system. you can not get a P0404 with this engine. If the same code return use a different scan tool to read the codes
