Powertrain DTC Summaries & Drive Cycles: 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 gasoline fueled, Jaguar X-TYPE, new lightweight aluminum-bodied XJ, S-TYPE and XK vehicles.

NOTE: Transmission P-codes are listed after the Engine P-codes.

The Denso 32-bit engine control module (ECM) has an aluminum 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 in Figure -Figure .
