Anyone????????

 

Come On Anyone Has A Idea????

P0453 Troubleshooting

1. Check the vacuum lines at the FTP sensor. Make sure they're not kinked, cracked, leaking, broken, clogged, etc.
Are the vacuum lines okay?
Yes - Go to step 2.
No - Repair or replace the bad vacuum line(s).

2. Reset the ECU. (Remove fuse #6 (15A) from the under-hood fuse box. Wait at least 10 seconds before putting it back in)

3. Remove the gas cap.

4. Turn the ignition switch ON (II)

5. Monitor the FTP sensor voltage with the HDS, or measure the voltage between a body ground and ECM/PCM connector terminal E14.
Is there about 2.5 volts?
Yes - Intermittent failure. System is okay, but check for loose wires or poor connections at the FTP sensor and the ECM.
No - Go to step 6

6. Turn the ignition switch OFF.

7. Put the gas cap back on.

8. Disconnect the FTP sensor 3-pin connector.

9. Turn the ignition switch ON (II)

10. Measure the voltage between FTP sensor connector terminals #1 and #2.
Is there about 5 volts?
Yes - Go to step 15
No - Go to step 11

11. Turn the ignition switch OFF.

12. Disconnect ECM/PCM connector E. (31-pin)

13. With a jumper wire, ground FTP sensor connector terminal #2

14. Check for continuity between ECM/PCM connector terminal E4 and body ground.
Is there continuity?
Yes - Swap your ECM with a known-good one and re-check. If the problem does not return, the problem was the ECM.
No - Repair an open in the wire between the FTP sensor and the ECM/PCM (E4)

15. Measure the voltage between FTP sensor connector terminals #2 and #3.
Is there about 5 volts?
Yes - Replace the FTP sensor.
No - Go to step 16

16. Measure the voltage between ECM/PCM connector terminals E4 and E14.
Is there about 5 volts?
Yes - Repair an open in the wire between the FTP sensor and the ECM/PCM. (E14)
No - Swap your ECM with a known-good one and re-check. If the problem does not return, the problem was the ECM.
