Code Definition

P1174 — Cam Sensor Fault

System: Powertrain  |  Type: Manufacturer-Specific  |  Make: Generic

About P1174

P1174 is a manufacturer-specific powertrain diagnostic trouble code. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

When P1174 is stored, the module has detected a sensor-related fault — the reported value from the named sensor is out of spec.

Scanning & clearing: A generic OBD-II scan tool will usually read and clear powertrain (P) codes. For live data, freeze-frame capture, and bi-directional tests you may need a more capable scan tool that supports the vehicle's ECM protocol.

P1174 is a manufacturer-specific code. The same code string on a different make may have a different meaning. Always confirm the code's definition against the vehicle's service information for the specific make and model under test.

Code Information

This code sets when the powertrain control module (PCM) detects a malfunction in the camshaft position sensor (CMP) circuit. The CMP sensor provides critical timing information for fuel injection and ignition system synchronisation. A failure can lead to misfires, rough running, hard starting, or stalling.
