CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM, Diagnostic DTC:P03352A, P033531

DTC Code	DTC Name
P03352A	Crankshaft Position Sensor "A" Signal Stuck in Range
P033531	Crankshaft Position Sensor "A" No Signal

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.

MONITOR DESCRIPTION

A DTC will be stored if any of the following occur:

The crankshaft position sensor signal (NE signal) is not received by the ECM when the engine is being cranked.
The engine stalls and the engine speed signal value decreases rapidly (under normal conditions the engine speed will decrease gradually).

Tech Tips

If no problem is found by this diagnostic troubleshooting procedure, check for problems by referring to the engine mechanical section.
The engine speed can be checked by using the GTS. To perform the check, follow the procedures below:

Connect the GTS to the DLC3.
Start the engine.
Turn the GTS on.
Enter the following menus: Powertrain / Engine / Data List / Engine Speed.

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.

Read freeze frame data using the GTS. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
