Throttle Body C2A1445 Electronic Air Assisted Fuel Injection XKR and X...
In 1999 Jaguar introduced a new advanced electronic air assisted fuel injection throttle body for the Jaguar XKR and XJR 4.0 Cars.
These are the key features of this electronic throttle body:
* Pedal Position Sensor
* Throttle Position Sensor
* Throttle Motor
* Fully motorised control of the throttle valve from the Engine Management System (EMS)
* Air Assisted Fuel Injection Control Valve
As all these components are controlled by the car’s EMS, if there is a problem with any one of these parts then the EMS can cause the car to suddenly stall or switch the car to ‘Fail Safe / ‘Limp Home Mode’ and seriously restrict and reduce the performance of the car. This can be very dangerous and disturbing when travelling at speed !. Common problems with this unit are associated with the pedal position sensor (PPS), throttle motor and throttle position sensor (TPS). Upon running a diagnostics check typical fault codes might be coming up as – P0121, P1121, P1222, and P1632
