Code P1702 Dodge Description
The P1702 code for Dodge vehicles indicates a correlation problem between the primary oil pressure sensor and the secondary oil pressure sensor. These sensors are crucial components of the engine management system as they monitor the oil pressure within the engine. The primary sensor is responsible for sending oil pressure information to the engine control module (ECM), while the secondary sensor acts as a backup in case the primary sensor fails.
Common Causes of P1702 Dodge
- Faulty oil pressure sensors
- Wiring or connector issues
- Low engine oil level
- Engine oil viscosity or quality problems
- ECM software or hardware issues
Symptoms of P1702 Dodge
- Dashboard warning lights indicating low oil pressure
- Engine knocking or ticking noises
- Poor engine performance
- Stalling or misfiring
- Oil leaks under the vehicle
How to Fix P1702 Dodge
- Inspect the oil pressure sensors: Check the primary and secondary oil pressure sensors for any damage or corrosion. Replace any faulty sensors.
- Check wiring and connections: Inspect the wiring harness and connectors for any signs of damage or loose connections. Repair or replace as needed.
- Verify engine oil level and quality: Ensure that the engine oil level is adequate and that the oil is of the correct viscosity and quality. Top up or change the oil if necessary.
- Clear the trouble codes: Use a diagnostic scanner to clear the P1702 code from the ECM memory after completing the repairs.
- Test drive the vehicle: Take the vehicle for a test drive to verify that the issue has been resolved and that the oil pressure readings are now accurate.
Cost to Fix P1702 Dodge
The typical repair costs for addressing the P1702 code can vary depending on the specific cause of the issue.
