About P1345

P1345 is a manufacturer-specific powertrain diagnostic trouble code recorded for Toyota vehicles. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

Scanning & clearing: A generic OBD-II scan tool will usually read and clear powertrain (P) codes. For live data, freeze-frame capture, and bi-directional tests you may need a more capable scan tool that supports the vehicle's ECM protocol.

P1345 is a manufacturer-specific code. The same code string on a different make may have a different meaning. Always confirm the code's definition against the vehicle's service information for the specific make and model under test.

Code Information

This DTC sets when the Engine Control Module (ECM) detects a misalignment or correlation fault between the crankshaft position sensor (CKP) and the camshaft position sensor (CMP) signals, indicating a malfunction in the Variable Valve Timing (VVT) system. The ECM commands the camshaft phaser through an oil control valve and expects a specific phase angle between the crank and cam signals to result. If the measured cam timing is outside the specified range or does not respond to control commands, the ECM logs this fault. The driver may notice rough idle, reduced power, poor fuel economy, a ratt...
