Jaguar P1371 Code Description
The Jaguar P1371 code refers to a problem with the ignition coil of engine cylinder 1. This code indicates that the ignition coil is activating too early, which can lead to misfires, irregular idling, and poor overall engine performance. The ignition coil is responsible for generating the high voltage needed to ignite the air-fuel mixture in the combustion chamber. When the ignition coil activates too early, it can cause the spark plug to ignite at the wrong time, resulting in inefficient combustion and potential engine damage.
