I've got a Toyota ECT ECU from a 1987 4Runner that is an AISIN brand, Toyota part # 89530-35170. A search for this part # on Google as well as several Toyota parts websites including Megazip.net and ToyotaPartsDeal.com produced no results. Known ECT ECU part #'s are:

• 89530-35070 (08/1985 - 01/1986)
• 89530-35160 (08/1986 - 08/1987)
• 84530-35080 (8/1985 - 01/1986) which was replaced by the 89530 - 35070

Since the part number 89530-35170 doesn't seem to exist, is it possible the label is a misprint where the -35170 was meant to be either -35160 or -35070? Any other possibilities?

I know nothing about Autos but could the 22RTE use another # because Toyota is good for that

Being it is the same part just a different number

Replaced by 89530-35070 just the up date waslost

 

This is quite possible. I remember coming across a part in the past with a part number molded into the plastic and nothing came up during a search. The part number was probably changed during production and never made it into the computer database.

What part number comes up if you call the dealer with your VIN?

 

Yep. But when I do a search for 89530-35170 (the number on my part) I get no hits.
It's a ghost number. I've never had this happen. I must be missing something.

 

89530-35160-84, which replaced 89530-35160 in a warranty repair. The -84 at the end indicates the part was re-manufactured.

 

I searched via Google - put the part number in along with Toyota.

Your other numbers came up with:
