Code P0339 2014 Toyota RAV4 Description
The sensor plate has 34 teeth and is installed on the crankshaft. The pickup coil is made of wound copper wire, an iron core, and a magnet. The crank angle 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 Engine Control Module (ECM) calculates the crankshaft position and engine speed. Using these calculations, the fuel injection and ignition timing are controlled. If there is no signal from the crankshaft position sensor despite the crankshaft rotating, the ECM interprets this as a malfunction of the sensor and the Diagnostic Trouble Code (DTC) will be set.
What are the Possible Causes of the DTC P0339 2014 Toyota RAV4?
- Faulty crankshaft position sensor
- Crankshaft position sensor harness is open or shorted
- Crankshaft position sensor circuit poor electrical connection
- Signal plate may be damaged
- Starter motor may be faulty
- Dead or weak battery
- Faulty Engine Control Module (ECM)
