DESCRIPTION
The crankshaft position sensor system consists of a crankshaft position sensor plate and a pickup coil. The crankshaft position sensor plate has 34 teeth and is installed to the crankshaft. The pickup coil is made of wound copper wire, an iron core and a magnet. The crankshaft position sensor plate rotates and, as each tooth passes by the pickup coil, a pulse signal is created. The pickup coil generates 34 signals per crankshaft revolution. Based on these signals, the ECM calculates the crankshaft position and engine speed. Using these calculations, the fuel injection and ignition timing are controlled.

1. DATA LIST
HINT:
The engine speed may be indicated as zero despite the engine running normally. This is caused by a lack of NE signals from the crankshaft position sensor. Alternatively, the engine speed may be indicated as lower than the actual engine speed if the crankshaft position sensor output voltage is insufficient.
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to ON.
(c) Turn the Techstream on.
(d) Start the engine.
(e) Enter the following menus: Powertrain / Engine / Data List / Engine Speed

Engine Speed |
Engine speed Min.: 0 rpm Max.: 16383 rpm |
500 to 600 rpm: Idling (shift lever in neutral, engine warmed up and A/C off) |
When the crankshaft position sensor is malfunctioning, "Engine Speed" is approximately 0 rpm or varies greatly from the actual engine speed. |

Lost Communication with ECM/PCM "A" Missing Message (U010087)
DESCRIPTION
The engine control unit and the transmission control unit are located inside
the ECM. The engine control unit intercommunicates with the transmission control
unit with the Controller Area Network (CAN).
If there is a problem in this intercommunication, the ECM stores a DTC.
