P2A67Alternative Fuel Tank C Level Sensor Circuit High
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- How the car detects it
- P2A67 is the high-side partner of P2A66: the tank C level voltage lies above anything a correctly working sender outputs at full. An unplugged connector, a broken signal or ground wire and a short to a supply voltage all push the input there. Roush names such faults for the high case of its propane senders and notes for the second-tank code P2068 that only the primary tank is then shown; for a third tank no such public text exists, and no manufacturer documents P2A67. Since a believed full tank C could leave the driver stranded, the module drops the value rather than display it. Look for a connector knocked loose during tank service and check ground continuity from sender to chassis.
