- Breakout box installed, Powertrain Control Module (PCM) connected.
- Rotunda Megameter or equivalent connected to the breakout box.
- Key "ON".
- Observe and record the frequency value displayed by the meter.
Mixture To Frequency Chart:
- Using the chart above, determine and record the frequency range for the percent of methanol value calculated in DE9.
- Does the FF sensor output signal have a frequency corresponding to the percent methanol value calculated in DE9?
Yes -- Remove breakout box. Replace the PCM. Rerun quick test. Quick Test Appendix (Detailed Testing Instructions)
No -- Remove breakout box. Replace the FF sensor. Rerun quick test. Quick Test Appendix (Detailed Testing Instructions)
