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.
Medium severity. Can I keep driving?Yes, if the engine is running properly, but keep the trip short and moderate, since it could stop starting. Do not continue if it stalls or jerks hard.
Bank 2 is the side without cylinder 1, so it only exists on V or boxer engines.
Symptoms
- Check engine light on
- Longer cranking before the engine starts
- Loss of power (cam timing held in its base position)
- Rough idle, occasionally stalling
Most likely causes
- Camshaft position sensor bank 2 faulty
- Connector or wiring of bank 2 corroded or open
- Tone wheel or phaser of bank 2 damaged
- Timing drive of bank 2 jumped
What to check, in order
