How to replace the fuel pressure sensor on a 3.6L engine on Cadillac CTS?

As a first step to replace the Fuel Pressure Sensor on a 3.6l engine one needs to relieve the fuel system pressure. Start by removing both the cross vehicle brace and Intake Manifold before taking off the foam insulator from the fuel rails. It is important to avoid touching the plastic sensor housing with direct force yet you can use its hexagon for the tightening or loosening process. A 27 mm socket will be used to remove the Fuel Pressure Sensor from the fuel injection Fuel Rail for disposal. Deplete all fuel from the Fuel Rail and sensor location before using a lint-free cloth to dry both the sealing cone inside the rail and its surrounding area. Check that the sealing cone remains free of fuel as well as debris while being burr-free. Apply gm p/n 12345610 (equivalent to Canadian P/N 993193) silicon-free engine oil to the threads and sealing cone in the Fuel Rail followed by new Fuel Pressure Sensor treatment with the same lubricant before installation. Screw the new Fuel Pressure Sensor into the fuel injection Fuel Rail but only achieve hand tight contact then remove it to apply lubrication once more. Finish the process by installing the sensor to the rail while tightening it to 33 nm (25 lb ft). Fasten the new Fuel Pressure Sensor onto the fuel injection Fuel Rail by torquing it to 33 nm (25 lb ft). The foam insulator should be installed before the Intake Manifold takes its place. The replacement of the Fuel Rail becomes necessary when a fuel leak develops from this area. The ignition should be turned on when the engine is off for two seconds before being turned off for ten seconds then turned on again with the engine off to check for fuel leaks. Everything will finish with reinstallation of the cross vehicle brace.

In Cadillac CTS vehicles, the Fuel Pressure Sensor is common known as a fuel tank pressure sensor which is responsible for measuring the pressure in the fuel tank and rail. Communicating this data to the powertrain control module (PCM), it helps in making fine-tuning of fuel delivery and subsequently optimising engine output. It is also seen that various forms of fuel pressure senor may be used in each of the CTS models out of the fuel tank pressure senor and the fuel rail pressure senor kind. A faulty sensor causes some of the common car problems like difficult engine start, low fuel economy and, in general, poor engine performance and these may be heralded by warning signs such as the check engine light. It is therefore important to give due attention to the Fuel Pressure Sensor so as to ensure efficiency and reliability of the vehicle in equal measure.
