What does code P1253 mean?

Q: What does code P1253 mean?

Fuel Consumption Signal Short To Ground. P1253 on a Volkswagen means the engine control module (ECM) has detected a short to ground on the fuel consumption signal circuit, which is the wire that carries fuel usage data from the instrument cluster or CAN gateway to the ECM. The ECM uses this signal for range calculation, trip computer accuracy, and some fueling strategies, so a shorted wire prevents it from receiving valid data.
