P2A29Alternative Fuel Tank Shutoff Valve C Control Circuit High

P2A29 is a generic powertrain code that indicates the control circuit for the alternative fuel tank shutoff valve 'C' is showing an abnormally high voltage condition. The powertrain control module (PCM) commands the valve to open or close and monitors the return circuit; when the voltage on the control circuit exceeds the expected threshold for the commanded state, the PCM sets this code.
