A co-worker has a 97 LX throwing a 401 code
About a year ago, I installed a new modulator as his original had a torn diaphragm and that worked fine until last week when the code came back
The EGR valve itself functions as it should when vacuum is applied, but the VSV doesn't click when voltage is applied
Told him I'd install it if he picked one up, but he's low on funds and asked if I could find him a used one
While searching EBay, I noticed a lot of the listings show that VSV's for other vehicles like Paseo, Tercel, Corolla, etc. are compatible, but although they look identical, the part numbers are different
I've seen them listed for as low as $15 bucks shipped, so I figured that would be his best bet IF they are in fact compatible
Can anyone confirm this?
If so, what other compatible vehicles should I look into?
