Circuit Continuity Jaguar XK II facelift

Testing & Diagnostics

Circuit continuity is checked by monitoring the commanded and the actual state of the EVAP canister purge valve. If the commanded and actual states do not match, a timer is started. If the states do not match within the timed period then a failure is registered. If the failure occurs on two drive cycles then the appropriate DTC is logged.
