Nissan Maxima 1993-1998 Repair Guide

General Information


Maximas with the VE30DE and VQ30DE engines use a distributorless ignition system that is controlled by the Engine Control Module (ECM). The ECM receives a signal from the crankshaft sensor, and processes the signal based on inputs from other various engine sensors. Then the ECM sends signals to each of the individual coils in the proper firing order.

This system is more efficient than a distributor, and has less moving parts. The high voltage coils are directly attached to each spark plug, allowing a higher energy spark within the cylinder. A high energy spark means a faster, more thorough burning of the air/fuel mixture, which produces more power and less
