The EVAP fuel-vapor temperature sensor signal sits above the upper plausibility limit — open signal line, brok…
The EVAP fuel-vapor temperature sensor signal jumps or drops out intermittently — usually a connector or chafe…
The fuel-fired auxiliary heater (used to warm coolant or DEF on cold start) has been disabled by the control m…
The DEF tank heater control circuit is open or has lost continuity — the PCM cannot drive the resistive heater…
The DEF tank heater control line reads below the expected voltage — short to ground or stuck-low driver.…
The DEF tank heater control line reads above the expected voltage — short to B+ or open ground. The sensor hea…
A leak has been detected in the DEF (urea) supply system — usually by a pressure-decay test after pump shutdow…
The DEF (urea) injection valve on bank 2, unit 1 does not respond to commands within the expected range — flow…
The control line that gates the DEF supply pump or the regeneration heating circuit does not respond as comman…
The fuel-fired auxiliary heater is operating but not delivering the expected heat output within the calibrated…
The exhaust gas temperature (EGT) sensor at position 2 on bank 1 — typically downstream of the catalyst or bef…
The EGT sensor at bank 1 position 2 reads below the lower limit. Common when the signal is shorted to ground o…

A general electrical fault is reported on reductant injection air-pressure sensor A — used on air-assisted DEF…
The reductant injection air-pressure sensor A reads inside the electrical range but does not match expected be…
The reductant injection air-pressure sensor A reads below its lower plausibility limit — short to ground or se…
A general electrical fault is reported on DEF level sensor A — open, shorted, or out of plausibility. Some tan…
DEF level sensor A reading is in electrical range but plausibility check fails — value sticks, jumps, or does …
DEF level sensor A reads below lower plausibility — short to ground. Wiring faults of this kind typically come…
DEF level sensor A reads above upper plausibility — open signal or short to B+. Wiring faults of this kind typ…
DEF level sensor A signal jumps or drops out intermittently — typically a corroded sender contact or wiring is…
