Hi S-diehl3,

Here are the diagnostic procedures for P1346. P1349 is not listed anywhere, can you reconfirm the code?

DTC P1346: VARIABLE VALVE TIMING (VVT) CIRCUIT RANGE/PERFORMANCE
CAUTION:If ECM replacement is instructed in following testing, always ensure ECM connectors and ground circuit are okay. If either are suspect, repair and repeat testing to confirm ECM malfunction.

NOTE:
Variable Valve Timing (VVT) sensor may also be referred to as camshaft position sensor.

NOTE:
Bank No. 1 refers to bank which includes cylinder No. 1. Bank No. 2 refers to bank without cylinder No. 1.

Circuit Description

The Variable Valve Timing (VVT) sensor consists of a signal plate and pick-up coil. The signal plate has one tooth and is mounted on each intake camshaft. The VVT sensor provides feedback to ECM in order to control intake valve timing. DTC is set when ECM detects a deviation in crankshaft position sensor and VVT sensor. Possible causes are:

" Mechanical system malfunction (timing belt stretched of timing belt teeth jumped).
" Defective ECM.

Diagnostic Aids
Using scan tool, read freeze frame data. Freeze frame records engine conditions when malfunction is detected.

Diagnosis & Repair
Check valve timing. Check for loose, stretched or jumped teeth of timing belt. If problem exists, repair as necessary. If problem does not exist, replace ECM.
