Tentative. Tentative: this code is present in the firmware, but its precise meaning is not established.

What it means

Like 19-02, this is a crank-sensor code on the later ECUs. The family is clear, but the specific condition that sets it is not reconstructed.

Conditions

Detection conditions

  • Reported by the 2007-2022 firmware under the crank-sensor family; the exact trigger is not identified.

Sets the fault when

  • Not established in the research.

Clears the fault when

  • Fix the underlying problem, then clear the stored codes with a diagnostic tool or the manufacturer’s reset procedure. If the fault is still present, the code returns the next time the ECU detects it.

Parts involved

  • Crankshaft position (CKP) sensor (by family)

Symptoms & likely causes

Possible symptoms

  • FI (check-engine) light on

Likely causes

  • A crank-sensor-related fault (specific cause not established)

Diagnostic guidance

Start with the crank sensor circuit and trigger wheel; the precise condition is unconfirmed.
