P1346 — Camshaft Position Out Of Range - Bank 1

System: Powertrain  |  Type: Manufacturer-Specific  |  Make: Toyota

About P1346

P1346 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.

When P1346 is stored, the module has detected a plausibility fault — the measured value is in the electrical range but is not consistent with expected operating behaviour; and a bank-specific fault, meaning it applies only to one cylinder bank of a multi-bank engine.

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.

P1346 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 that the camshaft timing for Bank 1 is outside the expected range, based on the correlation between the Camshaft Position Sensor (CMP) and Crankshaft Position Sensor (CKP) signals. This typically indicates a fault in the Variable Valve Timing (VVT) system, such as the camshaft not advancing or retarding as commanded, or a mechanical timing issue. The ECM monitors the actual cam phase against the commanded value and sets this code when the Bank 1 camshaft is stuck, lagging, or over advanced. The driver may notice rough idle, hesitation,...
