What Does P1350 Mean?
P1350, like P1345, indicates a malfunction in the camshaft position sensor (SGC sensor) circuit or a failure in the crankshaft-to-camshaft position correlation. This manufacturer-specific code is used on certain vehicle platforms to flag the same type of cam-crank synchronization error. The ECU has detected that the cam and crank signals do not maintain their expected phase relationship.
Safety Warning
A cam-crank correlation fault indicates potential timing component wear or failure. On interference engines, a jumped timing belt or chain can cause severe engine damage. Have the timing verified before driving further.
Common Causes
30%
Timing chain or belt has jumped one or more teeth
25%
Worn distributor drive gear (on distributor-equipped engines)
20%
Failed or degraded camshaft position sensor
15%
Stretched timing chain causing gradual timing drift
10%
Damaged CMP sensor reluctor ring or misaligned distributor
Diagnostic Steps
1
Use a scan tool to monitor the cam-crank correlation learned angle value. Compare to factory specification to determine the magnitude and direction of the timing offset.
2
On distributor-equipped engines, inspect the distributor gear and shaft for wear. Remove the cap and check the rotor for proper alignment with the CKP reference.
3
Inspect the timing chain/belt for proper tension. On chain-driven engines, check for audible chain rattle at startup and visual slack through an inspection opening.
4
Test the CMP sensor with an oscilloscope to verify clean, properly-timed signal edges relative to the CKP signal.
5
If timing components are worn, replace the timing chain/belt, tensioner, and guides as a set. Re-verify cam-crank correlation after repair.

The most common cause of P1350 (SGC (Cam Position) Sensor Circuit Malfunction/ Crankshaft Position - Camshaft Position Correlation) is: Timing chain or belt has jumped one or more teeth
Typical repair costs for P1350 range from $200 to $1,200, depending on the vehicle, location, and whether you do it yourself or go to a shop.
