## Description

Toyota Quality Assured, Genuine Toyota Parts OEM Only, Not After Market

Review: Perfect fit - Easy to install. Just like the original
Review: Solution to my intermittent check engine light. - Application: 2010 Toyota Tacoma TRD Sport DCSB I want to first point out that while this is an OEM product and arrived in a legitimate Toyota parts packaging, there are some subtle differences to the text on the cap. I’ve included some pictures (old OE cap on right and new on left) so you can see the texts differences. No big deal - doesn’t impact functionality but I’m a stickler for details so it is worthy of pointing out. As for my problem: I noticed about a year ago that my gas cap was not always giving me the “1-click” when I finished at the pump. I’d have to try several times before I felt like the cap was on correctly. A quick search on a Tacoma forum indicated that this is a common problem for owners. As time went on, I would get sporadic check engine lights. The codes were not always consistent with an EVAP leak or something that would point to the gas cap but resetting the ECU (disconnecting the battery to clear codes) and tightening the gas cap would keep the check engine light at bay for a few more weeks. Eventually, I decided to look up the OE gas cap part which brought me here and when I saw how cheap it was, decided to purchase. There are several off brand alternatives here on desertcart when you search the part number. They are cheaper but OE quality is worth an extra $3-4 dollars in my opinion. Install is a breeze. Grab some pliers if your old cap still has the tether in tact and yank it off the fuel door. Press fit the new tether in place and you’re ready to go. I’ve been check engine light free for several weeks now. The “1-click” is back and the difference was noticeable right away. Even comparing the old cap to the new one, it was easy to see how ineffective the rubber gasket had become. TLDR: Quality product that serves a basic function but could also save you a ton of hassle if you’re not mechanically inclined and your Toyota is throwing a check engine light pointing to a leaky gas cap.
