Circuit Operation
- The tachometer power is supplied from the ignition switch (IG) circuit.
- For vehicles with 2.4L engine, the tachometer detects the ignition signal by the engine control module < M/T > or power control module < A/T > via the ignition coils.
- For vehicles with 3.0L engine, the tachometer detects the ignition signal control via the distributor assembly.
