P1702 Jeep Code - Primary Oil Pressure Sensor / Secondary Oil Pressure Sensor Correlation
Quick Answer
The P1702 Jeep diagnostic trouble code indicates a problem with the correlation between the primary and secondary oil pressure sensors in the vehicle. Common causes include Faulty Oil Pressure Sensor: The primary or secondary oil pressure sensor may be malfunctioning, providing inaccurate readings to the vehicle's computer system, Wiring Issues: Corrosion, damage, or loose connections in the wiring harness connecting the oil pressure sensors to the ECU can cause communication issues, Low Oil Level: Insufficient oil levels in the engine can lead to fluctuations in oil pressure readings and trigger the P1702 code. 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 Jeep Description
The P1702 Jeep diagnostic trouble code indicates a problem with the correlation between the primary and secondary oil pressure sensors in the vehicle. Oil pressure is a critical component of a vehicle's engine operation, as it ensures that all moving parts are properly lubricated and functioning smoothly. The primary oil pressure sensor is responsible for monitoring the oil pressure in the engine and sending this information to the vehicle's computer system. The secondary oil pressure sensor acts as a backup to the primary sensor, providing redundancy in case the primary sensor fails.
Common Causes of P1702 Jeep
- Faulty Oil Pressure Sensor: The primary or secondary oil pressure sensor may be malfunctioning, providing inaccurate readings to the vehicle's computer system.
- Wiring Issues: Corrosion, damage, or loose connections in the wiring harness connecting the oil pressure sensors to the ECU can cause communication issues.
- Low Oil Level: Insufficient oil levels in the engine can lead to fluctuations in oil pressure readings and trigger the P1702 code.
- Oil Pump Problems: A failing oil pump can result in inadequate oil circulation, leading to inconsistent oil pressure readings.
- Engine Mechanical Issues: Internal engine problems, such as worn bearings or a clogged oil filter, can affect oil pressure and trigger the P1702 code.
Symptoms of P1702 Jeep
- 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.
- Inconsistent Oil Pressure Readings: Drivers may notice fluctuations in the oil pressure gauge on the dashboard, indicating a problem with the oil pressure system.
- Engine Misfires: A malfunctioning oil pressure sensor can lead to engine misfires or rough idling due to improper lubrication of engine components.
- Engine Stalling: In severe cases, the engine may stall or fail to start altogether if the oil pressure sensors are not providing accurate readings.
- Reduced Fuel Efficiency: A malfunctioning oil pressure sensor can impact the overall performance of the engine, leading to decreased fuel efficiency over time.
How to Fix P1702 Jeep
- Diagnose the Issue: Use a scan tool to retrieve the trouble codes and perform a visual inspection of the oil pressure sensors and wiring.
- Replace Faulty Sensors: If the oil pressure sensors are determined to be faulty, they will need to be replaced with new, OEM-quality sensors.
- Repair Wiring: Check for any wiring issues, such as corrosion or loose connections, and repair or replace damaged wiring as needed.
- Check Oil Levels: Ensure that the engine has the correct amount of oil and that the oil is clean and of the proper viscosity.
- Test Oil Pressure: Use a mechanical oil pressure gauge to verify that the oil pressure readings from the sensors match the actual oil pressure in the engine.
Cost to Fix P1702 Jeep
The cost of repairing a P1702 Jeep code can vary depending on the extent of the issue and the specific repairs needed. In general, replacing an oil pressure sensor can cost between $100 and $300, including parts and labor. If wiring repairs are necessary, additional costs may apply. Overall, the total repair cost for addressing the primary oil pressure sensor/secondary oil pressure sensor correlation issue can range from $200 to $500. It's important to note that labor rates at auto repair shops can vary, so it's advisable to obtain multiple quotes from reputable mechanics in your area.
