P0345 Quick Answer
Bank 2 camshaft position sensor circuit fault — applies to V-engine bank 2. Mirror to P0340 on the opposite bank.
What Does P0345 Mean?
Camshaft Position Sensor "A" Circuit (Bank 2). Bank 2 camshaft position sensor circuit fault — applies to V-engine bank 2. Mirror to P0340 on the opposite bank.
Symptoms
- No-start or hard start
- Random misfires (may favor bank 2 cylinders)
- Loss of bank 2 VVT functionality
Common Causes
- Failed bank 2 CMP sensor
- Open or shorted wiring
- Connector damage or corrosion
- Reluctor wheel damage on the bank 2 cam
Diagnosis Steps
You’ll need a scan tool capable of reading live powertrain data, a digital multimeter, and access to the wiring diagram for the specific platform.
- Check the bank 2 CMP signal at the connector with key on.
- Verify supply, ground, and signal continuity.
- Inspect connector and wiring for damage.
Possible Fixes
- Bank 2 CMP replacement
- Wiring repair
Can I Still Drive With P0345?
The vehicle will usually still drive with P0345 stored, but performance, drivability, or emissions will be degraded. The PCM may inhibit emissions monitors and limit closed-loop fueling adjustments. Drive to a workshop, but don’t ignore the code long-term.
How Serious Is This Code?
P0345 is a moderate-priority fault. It will not prevent the engine from running, but unaddressed it can cascade into related faults or damage downstream components such as the catalytic converter. Address within a few drive cycles.

FAQ
Will P0345 clear itself?
Only if the underlying fault was intermittent and self-corrected. Most root causes are persistent and require physical repair.
Can I clear P0345 without fixing it?
You can clear it with a scan tool, but it will return as soon as the fault condition reappears — typically within one or two drive cycles.
Is P0345 related to other codes?
Often, yes. Adjacent codes in the same circuit or system frequently set together — if P0345 is present, scan for related codes and address them as a group.
