#16 of 39 99 Tacoma 4x4 Check engine light by bdn1

Sep 27, 2009 (4:42 am)

I have had this annoying check engine light that will not go away. I recently changed both the up stream, and down stream O2 sensors. When the engine had to be re-built I added a NWOR Header, Volant cold air intake, and JBA cat back exhaust. I also changed out the cat at the time of the re-build due to the engine over heating a floating the head gasket, and seizing the rings. The truck runs great, I average about 24 mpg on the highway, and have no other problems. When the computer is scanned it come back with a catalyst code. Any ideas out there on a possible fix for this?

2001 Tacoma's Check Engine Light came on right before I took it for the state inspection. My mechanic was good enough to give me the code printout that reported "System Too Lean" and "Air/Fuel Ratio Sensor Circuit range" They suggested the thermostat which I cahnged with no effect. I'm now way out of date for inspection and need to renew my registration, guess I need an answer.

Did you ever find out what was causing this problem? I have the same thing except it is the left side.

#21 of 39 2000 toyota tacoma starting/idling issues by jamson

Mar 18, 2010 (12:33 pm)

Hi, I really hope someone can help me with this problem. My 2000 tacoma starts very difficult. Sometimes it doesnt even start. The engine turns over but only occasionally will fire. This problem has gotten worse since the cold weather last fall and has progressed over the winter. I usually get it started by bump starting it at which point it will not stay running unless I stay on the gas pedal. Once I drive the half an hour to work it will usually start but not always and it still is very hard to start. I really have to let it crank until it fires. The check engine light has been on and off intermittently but has remained on for the last month. One more thing, when it is cranking over and starts to fire, it does not always start, it will kinda backfire. Not a full on gunshot backfire and there is a strong gas smell. If it had a carburetor I would think it would be flooded. Has anyone else out there had this problem and if so what was the fix? Please help cause I do not want to get ripped off by the dealer if this is an easy fix. Thanks in advance.

#22 of 39 check lamp light by elaine67

Hello, my 98 tacoma has the check lamp light on. The manual told me to make sure that the gas was full and that the gas cap was on properly. They both are. It then said that it's something electrical, but didn't seem urgent. Can I wait a few days before taking it to the shop or should I go immediately? Thanks, Elaine

I had the same code come up on my 02 2.7 liter tacoma, i replaced the air-fuel sensor located in the exhaust pipe in front of the catalatic converter,its a little costly ,but, it solved my problem.One other thing before i began working on my truck i disconnected the ground cable from the battery, then reconnected it when i was done it cleared the code and the check engine light went off,also it would be wise to do this repair work on a cold engine. good luck.

I too have a check engine lightproblem with my 2000 tacoma. I found that it turns on and off each time I purchase gas. A mechanic in Ann Arbor , MI replaced a fuse in the fuse box under the hood. I don't remember which fuse it was bit i think it was the second or third from the bottom or side of box toward front of vehicle. He said the Tacoma has a prob;em with this fuse becoming fowled when one gases up. When fuse replaced the light goes off.
