DH17 - Continuous DTC 1125: Check For TP Circuit Input



Continuous Memory DTC 1125 indicates the TP sensor signal went below 9.80% (0.49 volts) or above 92.27% (4.60 volts) sometime during the last 80 warm-up cycles.

Possible Causes:
- TP sensor connector with poor continuity.
- TP harness with poor continuity.
- TP harness intermittent short.
- TP sensor internal electrical or substrate open or electrical short.

- Start engine and bring to idle.

- Run throttle up to 1500 rpm for 5 seconds.

- Key On, engine running.

- Access TP PID for a fault indication with a Scan Tool while lightly taping on TP sensor and wiggling harness connector to simulate road shock.

- Is the TP PID changing below the minimum 9.80% (0.49 volts) or above the maximum 92.27% (4.60 volts)?

YES -- DISCONNECT and INSPECT the TP sensor connector. If OK, REPLACE the TP sensor. Complete PCM reset to clear DTCs. Clearing Diagnostic Trouble Codes

Rerun quick test. Diagnostic Subroutines (DSR) - Extracting Codes

NO -- Go to DH18. DH18 - Check TP Harness to PCM For Intermittent Opens or Shorts
