How to Replace an EGR Valve Pressure Sensorby Carl Pruit
The Exhaust Gas Recirculation (EGR) valve pressure sensor of your vehicle is designed to regulate the pressure flowing through the EGR valve. The pressure sensor is located on the firewall and has two rubber vacuum hoses and an electrical wiring harness plugged into the front. If your sensor is faulty, you can replace it in about an hour to help the vehicle operate more efficiently.
Unfasten the negative battery cable from the battery post with an open-end wrench. Locate the EGR valve pressure sensor on the firewall of the vehicle. The pressure sensor is normally near the center, between the master brake cylinder and heater hoses on the firewall.
Remove the two bolts that secure the pressure sensor to the firewall with a socket wrench and take the sensor off the firewall. Disconnect the electrical wiring harness from the pressure sensor and unplug the rubber vacuum hoses from the sensor.
Dispose of the old EGR valve pressure sensor. Attach the rubber vacuum hoses to the new EGR valve pressure sensor and connect the electrical wiring harness to the sensor.
Attach the EGR valve pressure sensor to the firewall with bolts. Fasten the negative battery cable of the vehicle to the battery post.
Things You'll Need
- Open-end wrench
- Socket wrench set
- To avoid burns, let the engine cool down before attempting to replace the EGR valve pressure sensor.
