Q:
How to check and repalce the fuel tank pressure sensor in Chevrolet Tracker? Posted by Customer
A:
The fuel pressure sensor is a component of the Evaporative Emission (EVAP) control system on OBD-11 vehicles. It is located on top of the fuel tank and is responsible for detecting vapor pressure inside the tank. When the pressure reaches a certain threshold, it opens the tank pressure control valve and allows the vapor to migrate to the EVAP canister. However, if there is a malfunction in the system and the pressure exceeds the specified threshold, the sensor sends a voltage signal to the PCM, triggering a diagnostic trouble code. To check the sensor, it needs to be removed from the fuel tank and connected to three 1.5V batteries in series. The voltage between the "Vout" and Ground terminals should be around 2.5 volts. Additionally, a hand-held vacuum/pressure pump can be used to verify that the voltage decreases slightly when a vacuum is applied and increases slightly when pressure is applied. If the sensor does not function as described, it should be replaced. To replace the sensor, the fuel tank needs to be removed and the sensor bolts should be removed. The sensor should be inspected for clogs in the air vent hole and pressure passage, and the O-ring should be checked for damage. If necessary, the passages should be cleaned and the O-ring should be replaced. The sensor should then be installed and the bolts should be tightened to the specified torque.
