• Q: How to Replace a Fuel Pressure Sensor on a Fuel Injection Fuel Rail on 2008 Chevrolet HHR?

  A: The replacement of a Fuel Rail Fuel Pressure Sensor demands pressurizing the high side fuel system before executing the task. Use a 27 mm socket through the opening in the foam insulator to detached the fuel injector wiring harness electrical connector from the fuel injection Fuel Rail Fuel Pressure Sensor. The foam insulator should remain in its original position to prevent breaking. Apply the 27 mm socket through the foam insulator opening to reach the Fuel Pressure Sensor on the Fuel Rail but only use the socket to tighten or loosen the hexagonal attachment. This will prevent sensor damage. A shop towel lies underneath the sensor position before removing and discarding the aged sensor so fuel can escape. Check the Fuel Rail sealing cone for any contaminants after drying it. Apply gm p/n 12345610 silicon-free engine oil (Canadian P/N 993193) or equivalent oil to both the threads and sealing cone in the Fuel Rail as well as on the new fuel injection Fuel Rail Fuel Pressure Sensor. Begin with a hand transmission of the new sensor but afterward remove it for lubrication before reinstallation to 33 n.m (25 lb ft). Connect the electrical connector of the fuel injector wiring harness while installing new pressure fuel lines and the low side fuel pressure port cap. Pour an engine oil with no silicon gm p/n 12345610 (Canadian P/N 993193) or equivalent through the new fuel fill cap followed by another tightening step. Check for leaks by placing paper between the generator and sensor starting the vehicle for five minutes before shutting off and checking for paper wetness. Wetting during this test indicates that the procedure should be conducted again from the beginning.
