2002  2.0 DOHC Engine  P0340 Camshaft Position Sensor Circuit Malfunction

Study Guide Component Location Study Guide Description 1. General Description Study Guide The Camshaft Position Sensor (CMPS) is a sensor that detects the compression TDC of the NO. 1 cylinder. The CMPS consists of a hall type sensor and a target on the end of the intake camshaft. When the target triggers the sensor, the sensor voltage is 5V. If not, the sensor voltage is 0V. These CMPS signal is sent to the ECM and the ECM uses the CMPS signal for synchronizing the firing of sequential fuel injectors.

How to Repair Sometimes Coupe not Start

Study Condition:

1. Intermittent engine not cracking after an hour of parking.
2. Sometimes only the pre start will function for engine start.

Study Cause:

1. Due to PDM ( Power Distribution Module) intermittent malfunctioning.

Study Diagnosis :

1. Study Scan tool check
   =  The trouble was regarding on immobilizer.
2. Study Confirm the problem start the engine to test until the problem appear(OK confirm) but still the trouble for the second time will not registered and can not show to the GDS( Diagnostic Trouble System).
3. Study Now the was confirm and the engine will not start.
   = Check for the power from the starter relay. Fail No power.
   = At the same time no trouble code, Check for the power of Button Start and Smart Key System from the fuse to button switch OK.
   = Check the power supply from Button Start and Smart Key System to the PDM.OK
   = Check the PDM power to the main relay for starting system. Fail No power.

Study Guide and Replace parts

1. Replace PDM assembly.
2. more and more case for  you  to have a tips on Hyundai   trouble shooting
