Code P1373 Jaguar Description
The P1373 Jaguar diagnostic trouble code indicates an early activation of the ignition coil in cylinder 3. In a typical engine, the ignition coil is responsible for converting the low voltage from the battery into the high voltage needed to create a spark in the spark plugs. This spark ignites the air-fuel mixture in the combustion chamber, powering the engine. When the ignition coil in cylinder 3 activates too early, it can lead to misfires, rough idling, and overall poor engine performance.
