Code P1375 Cadillac Description
Cadillac diagnostic code P1375 (DTC) refers to the high voltage in the IC 24X reference circuit. This code indicates that the voltage on the ignition control module’s (IC) 24X reference circuit is higher than the specified parameters. The IC 24X reference circuit is a crucial component of the vehicle’s ignition system, responsible for providing a reference signal to the ignition control module. When this voltage is higher than normal, it can lead to various performance issues and potentially cause long-term damage if not addressed promptly.
Common Causes of Cadillac Code P1375
NOTE: The listed causes may not be a complete list of all potential issues, and there could be other causes.
- Faulty ignition control module
- Damaged wiring harness or connector in the IC 24X reference circuit
- Faulty crankshaft position sensor
- Problem with the powertrain control module (PCM)
- Electrical issues such as short circuits or corrosion in the wiring
Symptoms of P1375 Cadillac
- Check engine light is on
- Engine misfires or hesitations during acceleration
- Rough idle or stalling
- Decreased fuel efficiency
- Difficulty starting the engine
How to Fix Cadillac Code P1375
- Start by connecting a diagnostic scanner to the vehicle’s onboard diagnostic port to retrieve error codes and perform a comprehensive engine control module analysis.
- Inspect the wiring harness and connectors of the IC 24X reference circuit for any signs of damage, corrosion, or loose connections. Repair or replace damaged components as necessary.
- Test the ignition control module and crankshaft position sensor using a multimeter to check voltage and continuity. Replace faulty components.
- Clear the error codes from the engine control module’s memory using the diagnostic scanner and test the vehicle to ensure the issue has been resolved.
- If the P1375 code persists, further diagnostics may be needed to identify underlying issues with the PCM or other associated components.
