Electronic Engine Controls




Electronic Engine Controls

The electronic engine controls consist of the following:

- Accelerator Pedal Position (APP) sensor
- Barometric Pressure (BARO) sensor (internal to PCM)
- Camshaft Position (CMP) sensor (located on the left side of the engine)
- Crankshaft Position (CKP) sensor (located on the right side of the engine)
- Diesel Particulate Filter (DPF) sensor, if equipped (mounted on the DPF)
- Engine Coolant Temperature (ECT) sensor (located on the engine front cover)
- Engine Oil Pressure (EOP) switch (located on the oil cooler)
- Engine Oil Temperature (EOT) sensor (located on the oil cooler)
- Exhaust Gas Recirculation Temperature (EGRT) sensor - inlet (located on the RH turbocharger inlet pipe)
- EGRT sensor - outlet (located on the vertical EGR cooler)
- Exhaust Gas Temperature (EGT) sensor, if equipped (3 mounted in the exhaust system)
- Exhaust Pressure (EP) sensor and tube assembly (located on the LH valve cover)
- Fuel Rail Pressure (FRP) sensor (located under the RH valve cover)
- Fuel temperature sensor (located on the secondary fuel filter)
- Intake Air Temperature 2 (IAT2) sensor (located on the intake manifold)
- Manifold Absolute Pressure (MAP) sensor (located on the intake manifold)
- Mass Air Flow (MAF) sensor (located on the air cleaner)
- PCM (located on the RH bulkhead)
- Turbocharger actuator (located on the high-pressure turbocharger)
