INTRODUCTION

This document provides a summary for each powertrain Diagnostic Trouble Code (DTC) that may be logged on the Denso 32-bit engine management system. The Denso 32-bit engine management system is fitted to gasolinefueled, Jaguar X-TYPE, new lightweight aluminum-bodied XJ, S-TYPE and XK vehicles.

NOTE: Transmission P-codes are listed after the Engine P-codes. Use the search feature to find specific P-codes.

The Denso 32-bit engine control module (ECM) has an aluminium case with a steel lid. The module has a single electrical connector and the case dimensions are 175mm x 155mm x 40mm. 'Denso' is printed on the part number label. The part number is **** - 10K975 - **.

On all vehicles except the XK, the ECM is installed in the passenger footwell, through the bulkhead between passenger compartment and engine compartment. On the XK it is installed in the powertrain housing (a black plastic box with a screw-down lid), which is located at the back of the engine compartment on the passenger side of the vehicle.

NOTE: Not all DTCs may be logged by all vehicle types. Some DTCs changed at 04MY and 05MY and three DTCs (P0106, P0107 and P0108) were reallocated to a different component. The VIN change-point for each vehicle of these reallocated DTCs is detailed in the notes column of this summary.

DTCs are listed in numerical order and a key to the column headings is shown below:

Column Heading Explanation
DTC Diagnostic Trouble Code
Notes Details any care points relating to the failure; includes VIN change-points.
Indication 2-trip MIL means that the failure must be detected on two subsequent drive cycles for the MIL to illuminate. Any other lamp indicator will be recorded in this column. There may also be a message displayed on the instrument cluster while the failure is being detected that is not detailed in this document.
Default Action A description of any default action the module undertakes in response to the detection of the failure.
Possible Causes A list of possible causes of the failure.
CM pin The pin(s) (if any) on the control module that might be associated with the failure.
DTC Description The DTC description.
