1993 Ford F-150 XL, EGR Control Waveform
Posted to the Waveform Library on 3/5/2005

Solenoid after 30 minutes of continuous highway driving. Any stops or reduction in speed below what the PCM would be requesting EGR flow would 'reset the clock' and the solenoid would function fine UNTIL 30 more minutes of cruise.
