imschur Posted August 17, 2011 Report Share Posted August 17, 2011 Got a solid check engine light on my 2002 Tundra. Nearly 61700 miles. Im wondering if this a predetermined light based on milieage or something else. This vehicle was recalled for defective oxygen sensor. They were replaced two years ago.

6132expert Posted August 17, 2011 Report Share Posted August 17, 2011 Go by a local autozone or advance and get them t check it, but the light has to be on when you take it so do not try reseting the light by disconnecting the battery.

imschur Posted August 17, 2011 Author Report Share Posted August 17, 2011 Do they charge for this? Are their diagnostics pretty reliable? We have a brand new autozone just opened near my day job Quote Link to comment Share on other sites More sharing options...
6132expert Posted August 17, 2011 Report Share Posted August 17, 2011 There should be no charge at all, no commentment to buy from them at all. Yes, there scanner is as accurate as they come. Quote Link to comment Share on other sites More sharing options...
edgecrusher Posted August 17, 2011 Report Share Posted August 17, 2011 autozone will check it for free, o2 sensors aren't hard to replace if that's the problem. keep us abreast, i can talk you through most repairs, assuming you have the tools Quote Link to comment Share on other sites More sharing options...

Dusty44 Posted August 18, 2011 Report Share Posted August 18, 2011 When you go by Autozone, if you have not already done so, take a pencil and paper. The readout will be a bunch of numbers. Crosscheck the numbers against the repair manual list. Or post the numbers and we will try to give you a best guess. One of the main things that shows up is a loose gas tank cap. The numbers for that are many and the diagnosis is usually very vague. Be sure the tank cap is tight, reset the computer, see if it comes back. Sometimes the guy at Autozone will reset the computer for you. There are laws/rules about him pressing that button in some places. Please tell us what you got out of all this anyway? I have had a Camry since 1997; just bought my third one. The 2ND one broke its timing belt; the dealership found a short laundry list of things that needed repair and the cost was about equal to the value of the car. I found a buyer who took the 2000 Camry off my hands 'as is' with the result that I came out even as an equivalent to a passable trade and am now making payments on my third (a 2011) Camry. I am always interested in how maintenance and repair go on any and all Toyotas.My daughter's 2003 Corolla developed a light and a code for the oxygen sensor. She was trying to decide how to collect enough money and time to get it fixed; several weeks went by. Then the light went out by itself and a month later the car passed state inspection. I can only guess that it was dirt or oil on the sensor that burned off. ??? Quote Link to comment Share on other sites More sharing options...
imschur Posted August 18, 2011 Author Report Share Posted August 18, 2011 This is my first issue with this vehicle. I had it for 9 years July 15. Coincidentally I went to emissions two weeks ago. Quote Link to comment Share on other sites More sharing options...
98Z5V Posted August 18, 2011 Report Share Posted August 18, 2011 I've got two different OBD II code scanners - I can send you one to tackle this job on your own. It'll retrieve the code, you can search the code online, and then use the scanner to clear the CEL, and turn that bastard off. I can talk you through any repairs, too.Depending on what pops up as a code, it might lead to something else causing it. Example, leaking intake manifold gasket will cause a P030X code, indicating a specific cylinder misfire. It won't necessarily be a bad plug, or something with the ignition system causing that misfire, and you gotta backtrack to find out what's going on. Most things are easy, but some are a huge pain in the ass. <dontknow>Let me know, and I'll get the scanner in the mail to you. You can grab the specific code(s) here, once you retrieve them:http://www.obd-codes.com/trouble_codes/ Quote Link to comment Share on other sites More sharing options...

hobbesgunner Posted August 18, 2011 Report Share Posted August 18, 2011 Autozone will give you a printout of the codes and parts that would cause them....had them check my Honda few weeks ago...turned out they didn't sell the sensor I needed.. gave me the printout and recommended couple other places to check before the last resort....going back to the stealership .. :P Quote Link to comment Share on other sites More sharing options...
imschur Posted August 18, 2011 Author Report Share Posted August 18, 2011 Well when I went for emissions they never screwed the gas cap back on. The light is still on but Im guessing this is my issue. Quote Link to comment Share on other sites More sharing options...
6132expert Posted August 18, 2011 Report Share Posted August 18, 2011 If you have no gas cap then that is most likly the problem, these newer cars/trucks have to pressureize to an extent. Go get a cap and have them run the codes just to verify <thumbsup> Quote Link to comment Share on other sites More sharing options...
98Z5V Posted August 18, 2011 Report Share Posted August 18, 2011 Yep, a loose (or missing) cap will throw the Evap (Low) or Evap (High) leak codes... Emissions bastages... <laughs> Quote Link to comment Share on other sites More sharing options...
Dusty44 Posted August 20, 2011 Report Share Posted August 20, 2011 Very glad it wasn't serious!! If you disconnect the battery to clear the codes, and if you haven't already, oil the terminals and exposed metal and wires with either a few drops of full synthetic motor oil or use moisture displacing gun oil to stop or slow corrosion. Keep in mind that the white powdery corrosion is lead salts and is THE most toxic form of lead. Quote Link to comment Share on other sites More sharing options...
imschur Posted August 20, 2011 Author Report Share Posted August 20, 2011 Last night I learned a friend at the office has an OBD II device that reads codes and can reset the light. Disconnecting the battery is a last resort. My GPS has lost it's ability to back up properly to an external card.disconecting the battery results in memory loss.

6132expert Posted August 20, 2011 Report Share Posted August 20, 2011 If the problem is the gas cap or a sensor and there are no other issues then once the problem is resovled then after just I would guess 30 miles of drive time or sooner the light will go off on its on.

imschur Posted August 20, 2011 Author Report Share Posted August 20, 2011 Thanks, it will take me a bit to go 30 miles. Did I mention this is a 2002 with only 67000 miles. I dont travel far <laughs> Quote Link to comment Share on other sites More sharing options...
6132expert Posted August 20, 2011 Report Share Posted August 20, 2011 I hear ya on that, my toyota is a 93 2wd pick em up and it has 112000 on it. Quote Link to comment Share on other sites More sharing options...
CMAN Posted August 25, 2011 Report Share Posted August 25, 2011 Don't disconnect the battery. That will not turn off the light but it could set the alarm mode and disable the radio. Only a scan tool can turn off the light. Quote Link to comment Share on other sites More sharing options...
ssonb Posted September 4, 2011 Report Share Posted September 4, 2011 If you unplug the battery or clear the codes with a scantool you will set a po 1000 code(this code does not set a MIL) in the PCM and until the vehicle itself runs all of the IM monitors you will not pass an emission test.This process sometimes takes up to three days.Most of the problems with Toyota seem to be with the O2 or the AF ratio sensors and the EVAP system leaks.

imschur Posted September 14, 2011 Author Report Share Posted September 14, 2011 Well it appears to be an O2 sensor. I forgot to write down which one though <laughs> Going to verify tomorrow Quote Link to comment Share on other sites More sharing options...
98Z5V Posted September 15, 2011 Report Share Posted September 15, 2011 O2 or HO2 - those are the choices. The O2 sensors are before the catalytic converter, and the HO2 sensors are after. If you can remember what the code was, we can tell you which sensor is was. <thumbsup> Quote Link to comment Share on other sites More sharing options...
