P0345 on Toyota vehicles
Camshaft Position Sensor Circuit (Bank 2) — what it means on a Toyota, whether it's safe to drive, and the fixes by model and year.
P0345 on a Toyota means camshaft position sensor circuit (bank 2). Most vehicles stay drivable short-term, but diagnose it promptly. The most common cause is failed bank 2 camshaft position sensor (typically $100–$400). Pick your Toyota model below for its known failure patterns, recalls, and TSBs.
What does P0345 mean on a Toyota?
P0345 is the Bank 2 counterpart of P0340. The ECM cannot interpret the camshaft position sensor signal on the Bank 2 "A" camshaft — the signal is missing, out of phase with the crankshaft signal, or carrying electrical noise. Bank 2 is the cylinder bank that does NOT contain cylinder number 1, so P0345 only appears on engines with two banks: V6, V8, V10, V12, and flat / boxer layouts. An inline engine has a single bank and cannot set this code.
P0345 is a standardized OBD-II code, so its definition is the same on every Toyota. What differs by model and engine is which cause is most likely — pick your Toyota model below for a diagnosis tuned to its known failure patterns, recalls, and TSBs.
Is it safe to drive a Toyota with P0345?
In most cases a Toyota stays drivable for short trips with P0345 active, but diagnose and repair it promptly. This is a high-severity code — ignoring it can lead to further damage or a failed emissions test. Exact tolerance depends on the model and engine.
What causes P0345 on a Toyota?
| Cause | Likelihood | Estimated repair (USD) |
|---|---|---|
| Failed Bank 2 camshaft position sensor | Most common | $100–$400 |
| Damaged or corroded Bank 2 sensor connector | Common | $50–$250 |
| Chafed or broken Bank 2 sensor wiring | Common | $80–$350 |
| Oil leaking into the cam sensor port through a failed o-ring | Common | $80–$350 |
| Loose, slipped, or damaged Bank 2 camshaft reluctor wheel | Occasional | $300–$1,200 |
| Timing chain stretch on the Bank 2 side causing cam-crank correlation drift | Occasional | $800–$3,000 |
| Failed PCM input for the Bank 2 cam sensor circuit | Rare | $400–$1,500 |
Repair costs are typical US ranges and vary by Toyota model, model year, and labor rate. A diagnostic trouble code is a symptom, not a guaranteed failed part — confirm the root cause before replacing anything.
