Air Conditioning Not Cold, Malfunction Indicator Lamp On, DTC P0116 Set

ISSUE DATE: DECEMBER 2006

Affected Vehicles

2007 Isuzu Ascender

 

Condition:

Some customers may comment that the Air Conditioning (A/C) does not get cold enough. Others may comment that the Malfunction Indicator Lamp (MIL) is on. Technicians may find that Diagnostic Trouble Code (DTC) P0116 (Engine Coolant Temperature Sensor Performance) has been set in the Powertrain Control Module (PCM).

 

Possible Cause:

This condition may be caused by the software in the PCM that allows the P0116 to set. While the P0116 is active, the PCM will not allow the A/C compressor to engage.

 

Correction:

Reprogram PCM.

Service Procedure

Technicians are to reprogram the PCM in vehicles built prior to the following VIN breakpoint:

Vehicle Engine VIN of First Vehicle Built

With Updated PCM

Ascender 4.2L (VIN S) 72133238

 

The updated PCM calibration is available on TIS Version 29.0. The new calibration is entitled “New software with diagnostic enhancements for DTC P0483”. As always, make sure your Tech 2 is updated with the latest software version. Refer to the Engine and Powertrain Control Module Programming and Setup procedures in the Service Manual for further information.
