Component Inspection

Check FTPS

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

Monitor "FTPS" parameter on service data

SPECIFICATION:

SPECIFICATION

Pressure (kPa)	Output Voltage (V)
-3.75	0.5
0	2.5
3.75	4.5

Is the "FTPS" parameter on the service data O.K?
YES
- Go to step 2.
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 ECM
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 ECM and check for proper operation. If the problem is corrected, replace ECM 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 ECM. Before or after testing ECM on the vehicle, use this function before reusing the ECM
