Jaguar

1 interpretation
P1373
Ignition coil, cylinder 3 - early activation Jaguar · ignition Data confidence 80%

The control module detected a fault associated with the Ignition coil, cylinder 3 - early activation circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Jaguar.

Possible causes

  • Wiring
  • ignition coil
  • engine control relay
  • ECM
