APPS (Accelerator Pedal Position Sensor) DESCRIPTION The Accelerator Pedal Position Sensor (APPS) is located inside the vehicle. It is attached to the accelerator pedal assembly. OPERATION The Accelerator Pedal Position Sensor (APPS) provides the Engine Control Module (ECM) with two DC voltage signals which change as the position of the accelerator pedal changes. One of the DC voltage signals will be half the voltage of the other signal. REMOVAL CAUTION: D

CAN BUS COMMUNICATION DESCRIPTION The primary onboard communication network between microprocessor~based electronic control modules in this vehicle is the Controller Area Network (CAN) data bus system. A data bus network minimizes redundant wiring connections; and, at the same time, reduces wire harness complexity, sensor current loads, and controller hardware by allowing each senSing device to be connected to only one module (also referred to as a node). Each node reads then br
-
CRANKSHAFT POSITION SENSOR DESCRIPTION The Crankshaft Position Sensor (CKP) on the diesel engine is attached at the front / left side of the engine next to the engine harmonic balancer (crankshaft damper). OPERATION The Crankshaft Position Sensor (CKP) (5) is the primary engine speed indicator for the engine after the engine is running. The CKP contains a hall effect device. A rotating, notched target wheel (tone wheel) for the CKP is located behind the engine harm

GRID HEATER RELAY OPERATION The Engine Control Module (ECM) operates the heating element through the intake manifold air heater relay. Refer to the Diagnostic Procedures section for an electrical operation and complete description of the intake heater, including pre-heat and post-heat cycles. REMOVAL The intake manifold air heater relay (5) is located in the engine compartment. It attached to a bracket. This bracket is attached to the right battery tray (3). The mount
-
IAT TEMPERATURE & MAP PRESSURE SENSOR OPERATION The combination, dual function Intake Manifold Air Temperature Sensor/MAP Sensor is installed into the top of the intake manifold with the sensor element extending into the air stream. The IAT portion of the sensor provides an input voltage to the Engine Control Module (ECM) indicating intake manifold air temperature. The MAP portion of the sensor provides an input voltage to the ECM indicating turbocharger boost pressure.
-
INTAKE GRID HEATER OPERATION The air heater element is used to heat incoming air to the intake manifold. This is done to help engine starting and improve driveability with cool or cold outside temperatures. Electrical supply for the air heater element is controlled by the Engine Control Module (ECM) through the air heater relay. Refer to Intake Manifold Air Heater Relay for more information. A heavy-duty cable connects the air heater element to the air heater relay. This cable will
