Component Inspection

Check FTPS

IG "OFF" and connect scan tool to DLC (Data Link Connector).

Monitor "FTPS" parameter on service data

SPECIFICATION :

OUTPUT VOLTAGE SPECIFICATION

Pressure (kPa)	Output Voltage (V)
-3.75	4.5
0	1.5
1.25	0.5

Is the "FTPS" parameter on the service data O.K ?
YES
- Go to 2"Check PCM" as follows.
NO
- Substitute with a known - good FTPS and check for proper operation. If the problem is corrected, replace FTPS and go to "VERIFICATION OF VEHICLE REPAIR " procedure.

Check PCM
1. IG "OFF" disconnect FTPS connector
2. Connect Scan Tool and IG "ON" & ENG "OFF"
3. Select simulation function on scan tool.
4. Simulate voltage at terminal 1 of FTPS harness connector.

5. Does the signal value of FTP sensor change according to simulation voltage ?
  YES
  - Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair or replace as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
  NO
  - Substitute with a known - good PCM and check for proper operation. If the problem is corrected, replace PCM and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
  NOTE: There is a memory reset function on scan tool that can erase optional parts automatically detected and memorized by PCM. Before or after testing PCM on the vehicle, use this function before reusing the PCM
