85 Celica 22RE - Intermittent Low Power Condition [Actual vs False Lean O2 Testing]
This is a continuation of our engine install on my son Beau's 1985 Toyota Celica GT with a 2.4L 22RE engine. In this video we are able to duplicate the low power condition with testing centralized around the oxygen sensor signal and fuel pressure.
00:00 - oxygen sensor testing with a voltmeter
01:45 - false lean or actual lean test
04:05 - actual lean condition identified
06:20 - TPS idle contact switch stuck at 12v
08:30 - ECT test
09:07 - fuel pump cut-off switch test (VAF)
10:30 - VAF signal test
11:13 - fuel pressure testing begins
14:15 - fuel pump power and ground testing

    Paul I have been trying to figure out this for a while now hopefully you can answer it . When I was subscribed as member the slide and classes were great. But the ones on pull up and pull down sensor circuits seemed to be backwards from what everyone else was teaching including a couple books I bought. I know I must be missing something can you help. Your slides on pull up circuits the voltage comes externally from pcm and pull down IT’s sourced internally. All the information I have is the opposite 🤷🏼‍♂️🙋🏼‍♂️🙇🏼‍♂️ lost and confused. My ocd has too know 😵‍💫

    • @ScannerDanner
      @ScannerDanner День назад

      Yes sir. I teach it from what the switch does and refuse to teach it the other way. If a switch is connected to ground, what is the switch doing? It is pulling the signal voltage down (pull-down design in my book) Why would we ever call that a pull-up circuit. I don't care that there is a pull-up resistor inside of the ECM on that circuit. Make sense?
