Issue:
Some 2006 XJ range vehicles within the above VIN range, may exhibit a concern of malfunction indicator lamp (MIL) illumination and/or poor driveability, such as idle quality, hesitation, A/C inhibit at high ambient temperatures or poor performance. Diagnostic trouble codes (DTCs) P050B-85 (Cold start monitor), or DTCs P0131, P0151 (Upstream heated oxygen sensor circuit low voltage) may be present.
Cause:
The upstream heated oxygen sensor may experience sudden variations in temperature due to water droplets in the exhaust system. Under normal circumstances, this does not present an issue, but software calibration/sensor compatibility can result in the above DTCs being logged and the driveability issues described.
Action:
In case of a customer complaint of the above condition, refer to the procedures detailed in this bulletin.
Note:
Reprogramming the TCM will cause the driving style memory to be erased. It is advisable to inform the customer that the transmission will have been reset and may drive differently than expected until the TCM adapts to the customer's driving style.
