What is the reason for the unreasonable position of the Cruze exhaust camshaft?

[DeAnderson]

The reason for the unreasonable position of the Cruze exhaust camshaft is the exhaust camshaft position sensor circuit or incorrect vehicle timing, caused by insufficient camshaft oil pressure. Below are the relevant details: 1. Fault description: The fault description indicates an issue with the exhaust camshaft position sensor circuit. Check the data stream on the diagnostic software. Test method: Increase the throttle to see if the data changes; normally, there should be changes. Inspect the exhaust camshaft sensor and the ECU. 2. Solution: Replace the exhaust camshaft sensor with a known good one. If the fault light remains on after restarting, the sensor issue can be ruled out. After replacing the camshaft, readjust the timing to resolve the problem.
