Details of the Isuzu p1295 OBD Code

P1295 in Isuzu indicates a fault with the cylinder head temperature sensor circuit.

OBD code P1295 for Isuzu vehicles indicates a fault with the Electronic Throttle Control (ETC) system.

This code is triggered when the throttle position sensor detects a discrepancy between the actual throttle position and the position that the Engine Control Module (ECM) is commanding.

The ECM monitors the throttle position sensor signal to ensure proper engine performance and emissions control.

If the signal deviates from the expected range, the ECM will set code P1295.

Mechanic’s Tech Notes

This section provides detailed information on diagnosing and fixing Isuzu fault code P1295.

To diagnose OBDII code P1295 on an Isuzu, start by checking the transmission control module (TCM) power and ground using a multimeter.

Verify TCM communication over the Controller Area Network (CAN) using a scan tool.

If the TCM does not respond, reprogramming or reflashing may be necessary.

Visually inspect the wiring harness and connectors for any damage, and check for broken, bent, or corroded pins.

This thorough examination can help pinpoint the root cause of the issue and guide you towards an effective repair.
