✓Fact-checked. Built from OLP's spec database, then independently fact-checked line by line with every correction applied. Master-tech sign-off by Chris Hackleman is queued. Cross-check torque values against the factory manual, and stop if anything looks unsafe. How our data is made.
Replace the oil pressure sensor on the 8.0L V10 engine to restore accurate oil pressure monitoring.
Warnings
⚠Allow engine to cool completely before beginning work. Hot oil and engine components can cause severe burns.
⚠Some oil will leak from the sensor port during removal. Have shop towels and a catch pan ready.
ℹ️The oil pressure sensor is electrically live when the ignition is on. Ensure ignition is off before disconnecting.

Preparation
- Ensure engine is completely cool to the touch
- Park vehicle on level ground and engage parking brake
- Turn ignition off and remove key
- Open hood and secure with prop rod
- Locate the oil pressure sensor on the driver's side of the engine block, below the exhaust manifold near the oil filter
Procedure
- 1Disconnect battery negative terminalDisconnect the negative battery cable from the battery terminal to prevent electrical shorts during sensor removal. The battery is located in the engine compartment on the 1992 Viper.
- 2Access the oil pressure sensorThe oil pressure sensor is located on the driver's side of the engine block, positioned below the exhaust manifold assembly and near the oil filter housing. From underneath the vehicle or through the wheel well, identify the sensor with its single-wire electrical connector. The sensor threads directly into the engine block.
- 3Disconnect sensor electrical connectorPress the tab on the electrical connector and pull it straight off the oil pressure sensor. The connector may be tight due to age; wiggle gently if needed but do not force.
- 4Remove oil pressure sensorUsing the correct-size deep socket or wrench (verify against OEM specification) with extension and ratchet, loosen the oil pressure sensor by turning counterclockwise. Have shop towels ready as oil will drip from the sensor port once removed. Unthread the sensor completely by hand once loose and allow residual oil to drain into a catch pan or towels.
- 5Clean sensor portWipe away any oil from around the sensor port opening on the engine block. Use a wire brush to clean the threads in the engine block port, being careful not to allow debris to fall into the opening. Spray with brake cleaner if available and wipe clean with a shop towel. Inspect threads for damage.
- 6Prepare new sensorApply a thin coat of thread sealant (Teflon paste or equivalent oil-safe thread sealant) to the threads of the new oil pressure sensor. Do not use excessive sealant as it may contaminate the oil system. Avoid getting sealant on the sensor tip.
- 7Install new oil pressure sensorThread the new oil pressure sensor into the engine block port by hand, turning clockwise. Ensure the sensor threads in smoothly without cross-threading. Once hand-tight, use the correct-size deep socket (verify against OEM specification) and torque wrench to tighten the sensor to the OEM-specified torque.Torque specOil Pressure Sensor20 Nm (15 lb-ft)
- 8Reconnect electrical connectorPush the electrical connector firmly onto the new oil pressure sensor until it clicks into place. Tug gently to verify it is fully seated and locked.
- 9Reconnect batteryReconnect the negative battery cable to the battery terminal in the engine compartment. Tighten the terminal clamp securely.
- 10Check oil levelCheck the engine oil level with the dipstick. Add oil if necessary to bring level to the full mark, accounting for any oil lost during sensor removal. Refer to OEM documentation for the exact oil capacity of the 8.0L V10 (verify before adding oil).
Reassembly
- Reassembly is completed during the installation steps above
Verification
- Start the engine and verify the oil pressure gauge shows normal reading (typically 25-80 PSI depending on RPM and temperature)
- Inspect the sensor installation area for any oil leaks while engine is running
- Allow engine to reach operating temperature and recheck for leaks
- Verify no oil pressure warning light or abnormal gauge readings are present
- Turn off engine and perform a final visual inspection of the sensor connection
