In this video we explore how to test and replace the EVAP pressure sensor P0450. If you’ve been following this channel you know we have a number of EVAP repair videos available. This video will add to that collection.
Trouble code p0450 deals with an improper voltage signal from the EVAP pressure sensor to the ECM. This could be due to a bad harness connector, the pressure sensor or the EVAP canister vent control valve. (link below for this component)
This sensor is used with a number of components in throughout the EVAP system. The EVAP control system pressure sensor is located in the purge line. The sensor detects pressure inside the purge line and modifies the voltage signal sent from the ECM. As the pressure increases the voltage rises. This sensor is used for on board diagnostics.
Tools Used:
Safety Glasses
Digital Multi-Meter
Vacuum Pump (Mityvac)
10mm socket & ratchet to remove sensor from chassis.
