P1345 Isuzu Code - Crankshaft Position-Camshaft Position Correlation
Quick Answer
The Crankshaft Position (CKP) sensor is a permanent magnet generator, known as a variable reluctance sensor. Common causes include Engine mechanical condition-Valve timing off, Cam sensor or crank sensor are loose on their mounting, Faulty camshaft position sensor. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P1345 Isuzu Description
The Camshaft Position (CMP) sensor is triggered by a notched reluctor wheel built into the exhaust camshaft sprocket. The CMP sensor provides 6 signal pulses every camshaft revolution. Each notch, or feature of the reluctor wheel is of a different size for individual cylinder identification. This means the CMP and crankshaft position (CKP) signals are pulse width encoded to enable the Powertrain Control Module (PCM) to constantly monitor their relationship. This relationship is used to determine camshaft actuator position and control its phasing at the correct value. The PCM also uses this signal to identify the compression stroke of each cylinder, and for sequential fuel injection. The CMP sensor is connected to the PCM by a 12-volt, low reference, and signal circuit.
What are the Possible Causes of the DTC P1345 Isuzu?
- Engine mechanical condition-Valve timing off
- Cam sensor or crank sensor are loose on their mounting
- Faulty camshaft position sensor
- Faulty crankshaft position sensor
How to Fix the DTC P1345 Isuzu?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
Code Tech Notes
If a P0016 or P1345 is resetting without any engine performance concerns but the above information did not isolate a cause for the DTC, replace the Cam Phaser Actuator sprocket.
What is the Cost to Diagnose the Code?
Labor: 1.0
To diagnose the P1345 Isuzu code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.
