I don't know how many of you Tacoma guys/gals have this problem but mine never came with a locking fuel door so I've been making do with a locking cap for the last few years.

I'm curious though... has anyone had problems with these?
It just occurred to me that I *may* be having the CEL issues of the last year or so because of the cap.

I reset the code today and replaced the OEM cap. So I'll know for sure soon enough.

Anyone want to share their experiences with theirs?

 

taco my 89 doesn't have the cel code so no issue there, but i use one i my blazer, and have never had a problem with it

 

Tacoma Dude: Yes, the fuel cap can cause CEL's on a Taco. If it doesn't seal well enough, you can get CEL codes relating to fuel pressure / emissions-related stuff.

Stant is the OEM manufacturer for Taco caps. I've got a Stant locking cap on my '04 Taco, and it worked right out of the box.

However, I've seen claims that some people have had problems with aftermarket caps not quite fitting well enough to please the ECU. In these cases, it sometimes takes a replacement or two to get one that seals well enough.

I'm not aware of any source for a locking cap other than Stant.

 

Just an update - I put the OEM cap back on and reset the code.
It came back multiple times so the cap is not the issue.

I was hoping for an easy fix

 

You can buy them at auto zone for a couple dollars. Shouldn't be too hard to spare I wouldn't think

 

Runner owner here but just had to replace a bad cap. Get a leak in the system and it is sure to cause probbies.

 

I have one and have had it for years!
