What P0345 means
P0345 is the bank 2 counterpart of P0340: the intake camshaft sensor on the side without cylinder 1 – only on V and boxer engines with one cam sensor per bank – delivers no or too few pulses while the crankshaft turns in sync. GM uses the same criteria as for P0340, e.g. on the 3.0 twin-turbo V6 (LGW): 5.5 s or 4 s of cranking without a cam pulse, or fewer than 4 pulses in 3 s running, set after two trips. Ford checks the ratio of cam to crank events from 200 rpm, detected within 5 s. FCA lists P0345 among the cam sensor codes for which the synchronisation event data should be saved before replacing the sensor. Result: cam timing on bank 2 is switched off and power drops; the cam phase usually remains available from the bank 1 sensor.
P0345 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyMedium, DIY possible
- Typical labor0.5 to 3 hours
- Clears after repairAfter a drive cycle
Symptoms of P0345
- Check engine light on
- Longer cranking before the engine starts
- Loss of power (cam timing held in its base position)
- Rough idle, occasionally stalling
Common causes of P0345
- Most likelyCamshaft position sensor bank 2 faulty
- Most likelyConnector or wiring of bank 2 corroded or open
- PossibleTone wheel or phaser of bank 2 damaged
- Less likelyTiming drive of bank 2 jumped
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0345 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 3 | Area: ignition system or misfire. |
| 45 | The exact fault in that area. |
What to do next
- Note P0345 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0345
What does P0345 mean?
P0345 means "Camshaft Position Sensor A Circuit Bank 2". P0345 is the bank 2 counterpart of P0340: the intake camshaft sensor on the side without cylinder 1 – only on V and boxer engines with one cam sensor per bank – delivers no or too few pulses while the crankshaft turns in sync. It is a generic code, so it means the same on every make.
Is it safe to drive with P0345?
Drive gently and only to a workshop. With P0345 the car can go into limp mode (reduced power) to protect itself.
Will P0345 fail an emissions test?
Yes, it can. P0345 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P0345 to fix?
Difficulty: medium. A typical repair takes 0.5 to 3 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P0345 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
