Component Inspection

Ignition "ON" & Engine "OFF".

Measure voltage between terminal 3 of the sensor harness connector and chassis ground (Do not disconnect FTPS harness connector)

Specification: Voltage increases proportionally with decreasing pressure (Approx. 2.5V to 4.5V)

PRESSURE SPECIFICATIONS

Pressure (kPa)	-6.67	0	6.67
Output Voltage (V)	0.5	2.5	4.5

Is voltage within the specification?
YES
- Check for poor connection between ECM and component: backed out terminal, improper mating, broken locks or poor terminal to wire connection. Repair as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure
NO
- Check for cracks or damage in hose connecting canister and fuel pump. Repair or replace as necessary.
- 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
