1.) CEL on
2.) Scanned / 3 codes.#17862/ 17819/ 17831
3.) Checked circuit fuses, tested pump relay. All tested good
4.) Checked for voltage at SAI pump, 12v at pump but pump inoperative
5.) Removed pump & took apart
6.) Pump was seized and burnt at motor brush locations/ housing w/small
amount of melt. Plastic brush holder in motor completely fried.
7.) Bought & installed new pump / cleared codes
8.) New pump failed within 50 miles
9.) Tested new pump. Isolated it, applied 12v, inoperative
10.) Scanned system, same codes found
Notes: On engine shut down after initial test drive noticed SAI pump was
running with engine off. Thought this was odd.
Question: Would a bad exhaust gas temp sensor in bank #1 cause the OEM
pump to fry?
How do I test this sensor with a DVOM & what are the specs that
I need to look for?
have the same problem?
