Glow Plug/Heater Circuit "A"

DTC P0380, sometimes indicated as P038000 is an OBD diagnostic trouble code indicating a generic fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the ignition system causing glow plug/heater circuit "a".

This code is set when the PCM detects a problem with the glow plug or heater circuit.
Possible causes include a bad glow plug or heater, a bad glow plug or heater control module, a short in the glow plug or heater wiring, or a failed PCM.
The most common solution is to replace the glow plug or heater. If the problem is caused by a bad glow plug or heater control module, the module can be replaced. If the problem is caused by a short in the glow plug or heater wiring, the wiring can be repaired. If the PCM is bad, it can be replaced.
