How to Check P0340 CMP of Hyundai Sonata EF

Study Guide and General Description

 

2002  2.0 DOHC Engine  P0340 Camshaft Position Sensor Circuit Malfunction

 

Study Guide Component Location

clip_image004

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.

 

2002   2.0 DOHC  Engine  Unleaded GEN(Siemens)  P0340 Camshaft Position Sensor Circuit Malfunction

 

Study Guide Terminal and Connector Inspection

1.

Study Guide Many malfunctions in the electrical system are caused by poor harness(s) and terminals. Faults can also be caused by interference from other electrical systems, and mechanical or chemical damage.

2.

Study Guide Check the following conditions:

(1)

Study Check for damaged harness and terminals: contact resistance, oxidation, bent or broken terminals.

(2)

Study Check for poor connection between ECM and component: backed out terminal, improper mating, broken locks or poor terminal to wire connection

 

Use a suitable male pin to ensure that contact in sockets is good. The pin should remain in position when pulled gently.
