Checking cables
Check the camshaft reset valve resistance between #1 and #2, resistance should be approximately 3.7 Ξ©.
Check the signal cable between engine control module (ECM) #A13 and camshaft reset valve #2 for a short-circuit to supply voltage according to Short-circuit to supply voltage. Permanent faults .
Remedy as necessary
