This is a great review of section 3 material in my book, specifically about testing a ground side switched solenoid. I kept it simple this time, doing all my circuit checks with just a digital multimeter and test light. Remember that all the methods shown can be successfully applied to ANY ground side switched output.
Engine Performance Diagnostics chapter 3 pages 2 – 19
– check engine light (P0443 and P0455)
– replacing the purge solenoid
– how to find the evaporative emissions purge solenoid by following fuel supply lines
– how to safely T-pin a computer controlled output
– testing a ground side switched solenoid with a digital multimeter and test light
– using a bi-directional test to confirm control circuit and driver integrity
– scan tool
– digital multimeter
– LED test light
– (Chapter 3) Transistors, Solenoids, Computer Controlled Output Testing
– How to test a computer transistor driver (with a scan tool)
– How to test a computer transistor driver (without a scan tool)
– How to test a computer controlled solenoid (energizing the circuit manually)
– How to test a fuel injector circuit with a noid light (a ScannerDanner Premium video)
– How to test a computer controlled solenoid – power/ground side identification
For more information on this topic, I have written a “field manual” called Engine Performance Diagnostics which is available at www.scannerdanner.com as an eBook or paper book.
