How to Locate the Camshaft Position Sensor on a 2011 Chevrolet HHR 2.2L with P0016 Fault Code?
I own a 2011 Chevrolet HHR with a 2.2L engine, and my vehicle will not start. The check engine light is triggered by fault code P0016 — which indicates a Crankshaft Position (CKP) and Intake Camshaft Position (CMP) sensor correlation issue. I recently replaced the camshaft position sensor, but after doing so, the crankshaft position sensor error code appeared. I'm now unsure whether I installed the correct sensor or if my work caused the problem. I need help identifying the exact location of the intake camshaft position sensor on this model and understanding why replacing it triggered a P0016 code. The issue seems to stem from a mismatch between the crankshaft and camshaft sensors' readings at Top Dead Center (TDC). I want to ensure that I replaced the correct component and that my installation was done properly. Could someone confirm where the intake camshaft position sensor is located on a 2011 Chevrolet HHR? Additionally, what are common causes of P0016 in this vehicle model?
It sounds like you may have replaced parts without fully diagnosing the root cause. Currently, your only fault code is P0016 — a Crankshaft Position (CKP) and Intake Camshaft Position (CMP) correlation issue. This means the two sensors are not agreeing on TDC position. The error appeared after you replaced the CMP sensor — this suggests that either the wrong sensor was installed or there's an underlying wiring/connector problem. Could you clarify what conditions led to replacing the sensor? Which specific intake camshaft position (CMP) sensor did you replace? Please double-check your work: ensure all connectors are securely attached, no pin damage, and that wiring is intact. A loose connection or damaged harness can mimic this fault code.
