Component Inspection

Component Inspection

1. Ignition "ON" & Engine "OFF".
2. Measure voltage between terminal 2 of the sensor harness connector and chassis ground (Do not disconnect FTPS harness connector)
A. Specification: Voltage increases proportionally with decreasing pressure (Approx. 2.5V to 4.5V)









3. Is voltage within the specification ?
YES
1) Go to "Purge Control Solenoid Valve (PCSV) Inspection" procedure
NO
1) Check for cracks or damage in hose connecting canister and fuel pump. Repair or replace as necessary.
2) Check for open or short in FTPS harness. Repair as necessary. If OK, test with a new FTPS and check for proper operation. If problem is corrected, replace FTPS and go to "Verification of Vehicle Repair" procedure
