Circuit/System Description

WARNING: This page is about a different variant/trim than selected.

Each camshaft position (CMP) sensor produces a 4X signal for each revolution of the camshaft. This signal is used for startability. If the engine control module (ECM) does not receive a crankshaft position (CKP) sensor signal, the engine should still start based off of the information from the CAM. The CMP is connected directly to the ECM and consists of the following circuits:

A 5-volt reference circuit
A low reference circuit
A CMP sensor signal circuit

The ECM runs 2 tests to diagnose the CMP sensor performance system. It uses a Near Engine Start, CMP Fast Event Based, test and an After Engine Start, CMP Slow Event Based, test. The Near Engine Start, CMP Fast Event Based, test runs first upon or during start-up. If the test fails, it will set DTC P0341. If the test passes, it will initiate the After Engine Start, CMP Slow Event Based, test and runs this test continuously unless it detects an error.
