Element inspection

WARNING: This page is about a different car, the 2004 Mazda RX-8. However, it is still accessible from the selected car via links, so may be relevant.

Verify using an oscilloscope that the wave pattern for the turbine sensor signal that is input to TCM terminal 2G is the same as the reference wave pattern.
- If the actual pattern of the turbine sensor signal is not the same as the reference pattern, inspect and repair the following items:

- Connected terminals: 2G (+) and 2M (-)
- Equipment setting: 5V/DIV (Y): 250 microseconds/DIV (X)
- Measuring conditions: M range, 1st gear at 20 km/h {12 mph}

Verify the wave pattern of the turbine sensor signal again, and if the malfunction is not resolved, replace turbine sensor.
