To diagnose wiring issues causing the check engine light to stay on in a Chrysler PT Cruiser after replacing the exhaust sensors:
1. Check Diagnostic Trouble Codes (DTCs): Use an OBD-II scanner to read the current codes. For example, code P0304 indicates a cylinder 4 misfire.
2. Inspect Wiring to Sensors: Visually inspect the wiring connected to the camshaft sensor, exhaust sensors, and surrounding components. Look for damaged, frayed, or corroded wires.
3. Test Sensor Connections: Ensure all connectors are securely attached and free of corrosion or bent pins.
4. Check for Previous Repairs: If wiring was previously modified, verify it was done correctly. Poor splices or wrong connections may cause intermittent faults.
5. Use a Multimeter: Test continuity and voltage in the suspect wires to ensure proper signal transmission.
6. Inspect Related Fuses: Check the fuse block for any blown fuses that could affect engine sensors or the powertrain control module.
7. Monitor Live Data: Use a scan tool to observe real-time sensor readings and identify inconsistencies.
If issues persist, have the system inspected by a qualified technician.
