Hi Guys! I'm trying to figure out a random appearing code 32 on my 94 5.7L.
I've pulled out the EGR valve and it looks pretty clean --it holds open with vacuum. How do I test the EGR solenoid? Should I be able to get an ohm reading between pnk/blk and blk/wht to test the coil? I was unable to get anything --not sure if I'm using the meter correctly.
Also, I wasn't able to get vacuum from the TBI's 'S' Port shown below at idle (I did not check at open throttle) --and I also was unable pull vacuum through the EGR solenoid to the EGR valve. Does the coil need to be energized before vacuum can flow to the EGR valve? I'm guessing vacuum was probably bleeding off through the vent filter end cap and it needs to be powered up for that to be checked.
Thanks in advance for any advice you have to give.
