Component Inspection
1. Reconnect FTPS connector
2. Ignition "ON" & Engine "OFF".
3. 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)
4. Is voltage within the specification ?
YES
1) 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
1) Check FTPS for contamination, deterioration, or damage. Substitute with a known-good FTPS and check for proper operation. If the problem is corrected, replace FTPS and then go to "Verification of Vehicle Repair" procedure.
