Genuine Toyota (77300-33070) Fuel Tank Cap Assembly

It is likely that you need a new gas cap if your Gen 3 Toyota 4Runner is getting the dreaded CHECK ENGINE light. What is the reason for this? There is no way to know. You can see what I look like in the The first is bad, and the second is good This item is the old one, and the old one is this one. There are no other traces of a Toyota logo on this fuel cap. Three different gas cap changes in the past 13 years have resolved my Check Engine light issues! I own a 2005 Toyota 4Runner Sport with a V8 engine. My maintenance records show I replaced my gas cap at 35K, 74K, and however, there were multiple illuminated warning lights on my dash, including the CHECK ENGINE and VSC TRAC. THIS GAS CAP IS FOR SALE & I have a check engine light. Please fix it!.

When I installed it on my 2003 Tundra, I found it to be a very reliable fuel cap. Towards the end of a year of use in my truck, I noticed that it occasionally lit up EVAP codes. Seeing as the cap was reasonably new, I immediately chalked it up to me not tightening it after filling it I'd had the problem for about 6 months, but it was getting more frequent, to the point where I went to the dealership to get another one. When I opened the dealership cap, the first thing that I noticed was that it arrived sealed in a package with a manufactured date. It was also nice and soft to touch due to being well oiled. The Amazon cap did not have a manufactured date. During that period, the gasket was not oiled, and it felt hard to the touch. (I should have returned it at the time, but since it worked, I didn't return it). With the dealership cap and no codes for over a year, it's really time for a tuneup. I suppose the takeaway is that you can save some money on Amazon caps, just be sure to double-check the manufactured date and the rubber gasket that is part of the package.

A white background for the letters is not acceptable There is a very faint gray-blue tone to this The letters are black on black and I can barely make them out. My engine light is on because the tether was so short that it pulled in on my hand before the first click. And now the fit is poor, the tether is so short that the door is pulled in on my hand just before the click. No matter what you do, it won't go away. In order to purchase the real thing, I'm going to a Toyota dealer tomorrow.

Fuel cap fits and works just like an OE part, so it was a perfect fit and replace. An evaporative emissions leak in our 2007 4Runner was displaying two trouble codes, which caused a bit of frustration. In this model truck, traction control is turned off by default whenever the check engine candle is lit for any reason, and it cannot be switched back on again until the problem is fixed. The Toyota concept is stupid (which is why Toyota didn't implement it). I was able to clear the codes instantly after I turned on the fuel cap. There is no good reason for the factory fuel caps to fail after 100 miles Afterward, it must be replaced with a new one after 150k miles. It seems to be a common problem in Tacomas and 4Runners. It's likely that other Toyotas are as well. Dry seals are incapable of maintaining system pressure and will stop functioning when they dry out. It was only a matter of replacing the cap that fixed the problem. It comes with a single piece of leather that secures it to the vehicle when opened which is one of the added benefits of buying the O. E. equipment cap. This feature is not available on aftermarket caps. In the event that your Toyota is throwing a trouble code related to an Evap problem, try this first.

It was enough to scare me when the engine check light came on my '05 4Runner. In fact, I had to take my state inspection, and the car failed due to "leaking emissions. " The technician said this most likely meant my fuel cap was faulty. The new one arrived and I changed my old one. I began driving the 100 miles that were required before I was allowed to reinstall it Submitted for testing. A few miles later, the lights were gone and on re-entry, there were no more lights During the test, the car passed with flying colors. The last time I had this inspected was a year ago (since I will have to have another inspection), and it continues to work.

Occasionally, I was able to drive my vehicle with no warning lights on the dash at the same time, but it seemed to be operating smoothly. Well, my husband, who is an auto tech, would check the codes and reset them. According to my husband, the gas cap hadn't been tightened properly, and our college-aged children did it the wrong way I have a daughter of this age. I was surprised to find that the gas cap was as securely attached as I had seen it. my husband reset everything to take care of the issue, and the warning light came back on just a couple of days later. As a result of some internet research, I discovered that gas caps simply wear out over time. Since I replaced the gas cap, warning lights have not appeared and our daughter's situation has been resolved.
