How to Check and Study CMP Sensor of Santa Fe

2003  G 2.0 DOHC  Engine  Unleaded GEN  P0340 Camshaft Position Sensor Circuit Malfunction

Study Terminal and Connector Inspection

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

2.Study 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

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

3.Study Has a problem been found?

YES

1)Study Repair as necessary and go to "Verification of Vehicle Repair" procedure

NO

1)Go to "Power Circuit Inspection" procedure Study .
