XK-8 Convertible (X100) V8-4.0L (AJ26) (1997)
-
sends the ECM a signal indicating throttle plate angle
-
is the main input to the ECM from the driver
-
is a dual Hall effect device mounted on the motor end of the throttle body
Two additional sensors are attached to the throttle body to provide additional feedback to the ECM a mechanical guard position sensor and an
accelerator pedal position sensor.
Camshaft Position (CMP) Sensor
-
sends the ECM a signal indicating camshaft position for fuel synchronization purposes
-
is a variable reluctance device mounted on bank 2 cylinder side face
-
generates a signal when the ring fitted to the bank 2 inlet camshaft passes the sensor
Crankshaft Position (CKP) Sensor
-
is a variable reluctance device mounted on the engine oil pan
-
generates a signal when the drive plate passes the sensor
-
sends the ECM signals indicating crankshaft position and engine speed
-
is essential for calculating spark timing
Engine Coolant Temperature (ECT) Sensor
-
sends the ECM a signal indicating the temperature of the engine coolant
-
is a temperature dependent resistor with a negative temperature coefficient (resistance changes inversely with respect to temperature) and is
constantly monitored by the ECM
Intake Air Temperature (IAT) Sensor
