P1460 Mercury Code - Wide Open Throttle Air Conditioning Cutoff Circuit Malfunction
Quick Answer
The Powertrain Control Module (PCM) monitors the Wide Open Throttle A/C Cut-Off (WAC) circuit. Common causes include Faulty Wide Open Throttle A/C Cutoff (WAC) Relay, Wide Open Throttle A/C Cutoff Relay harness is open or shorted, Wide Open Throttle A/C Cutoff Relay circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
