Any suggestions on additional tests?
Here's a recap of my test methods, with key in on position:
When I tested the low side sensor - using a multi-meter I touched the red lead to the paperclip in connector and black lead to the battery negative post.
Same with ECM pin 14 test - inserted paperclip in back of harness, plugged harness into ECM, red to paperclip, black to battery negative post
Same process with high side sensor.
Was my test correct?
