P1702 RAM Code - Primary Oil Pressure Sensor / Secondary Oil Pressure Sensor Correlation
Quick Answer
The P1702 diagnostic trouble code (DTC) indicates a correlation issue between the primary oil pressure sensor and the secondary oil pressure sensor in a vehicle. Common causes include Faulty Oil Pressure Sensors: A malfunctioning primary or secondary oil pressure sensor can trigger the P1702 code, Wiring Issues: Damaged or corroded wiring connections between the sensors and the ECM can cause communication problems, Low Oil Level or Pressure: Insufficient oil in the engine or low oil pressure can lead to inaccurate readings from the sensors. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P1702 RAM Description
The P1702 diagnostic trouble code (DTC) indicates a correlation issue between the primary oil pressure sensor and the secondary oil pressure sensor in a vehicle. The primary oil pressure sensor is responsible for monitoring the engine's oil pressure and sending this data to the engine control module (ECM) to ensure proper lubrication. The secondary oil pressure sensor serves as a backup to provide redundancy in case the primary sensor fails.
Common Causes of P1702 RAM
- Faulty Oil Pressure Sensors: A malfunctioning primary or secondary oil pressure sensor can trigger the P1702 code.
- Wiring Issues: Damaged or corroded wiring connections between the sensors and the ECM can cause communication problems.
- Low Oil Level or Pressure: Insufficient oil in the engine or low oil pressure can lead to inaccurate readings from the sensors.
- Clogged Oil Passages: Blockages in the oil passages can restrict the flow of oil and affect sensor readings.
- Malfunctioning ECM: A faulty engine control module may not be able to interpret the data from the oil pressure sensors correctly.
Symptoms of P1702 RAM
- Illuminated Check Engine Light: The most common symptom associated with the P1702 code is the illumination of the Check Engine Light on the vehicle's dashboard.
- Engine Misfires: Inaccurate oil pressure readings can lead to engine misfires and rough idling.
- Loss of Power: The vehicle may experience a loss of power or hesitation during acceleration.
- Engine Overheating: Insufficient oil pressure can result in the engine overheating due to inadequate lubrication.
- Engine Knocking: A knocking noise coming from the engine can indicate issues with oil pressure.
How to Fix P1702 RAM
- Diagnose the Issue: Use a scan tool to read the P1702 code and perform a visual inspection of the oil pressure sensors and wiring.
- Replace Faulty Sensors: If the sensors are determined to be faulty, replace them with new ones that meet the manufacturer's specifications.
- Check Oil Level and Pressure: Ensure that the vehicle has the correct amount of oil and that the oil pressure is within the recommended range.
- Clear the Code: After making the necessary repairs, clear the code from the ECM's memory using a scan tool.
- Test Drive: Take the vehicle for a test drive to confirm that the issue has been resolved and that the Check Engine Light does not reappear.
Cost to Fix P1702 RAM
The cost of repairing the P1702 code can vary depending on the specific cause of the issue and the make and model of the vehicle. On average, the parts required for this repair, such as oil pressure sensors, can range from $50 to $200. Labor costs can add an additional $100 to $300, depending on the shop's hourly rate and the complexity of the repair.
