I have the 03 v8 with 58k,, I started to get the po156 code for check engine. I replaced the correct sensor but just received the same stating "circuit malfunction". ive read here that there could be a heat issue to close to other pipes or something like that. Any ideas would be grand at this point. cat system going bad??

Replying to: ppisano (Jun 07, 2006 6:20 am) I have a 2000 Tundra. Last week the check engine light came on. My mechanic got a po135 code. He said it was for an oxygen sensor problem. He's a toyota mechanic but not a dealer. He heard there was an issue with Tundra oxygen sensors and suggested I contact toyota to see if it was a recall. If it was covered it could save me $250 plus labor. He's an honest guy. I tried the toyota web site, 800 number and the local dealer and none had any notices or recalls. I spoke with him today and he said try again, he thought there was a notice or something but he doesn't have any more information. He said some bad parts don't get recalled, they call it a campaign? They won't contact all the owners and offer the repair but if you ask they'll pay for it. At the least we can get counted as another owner with the problem that may eventually lead to a recall or campaign. I'm going to try again to see if I can find any assistance. I'll keep you posted. Please let me know if you learn anything. If anyone else has information to add it would be appreciated.

Replying to: woodgreenfarms (Jun 07, 2006 11:32 am) I replaced the spark plugs, I cleaned the KN mass air flow sensor. 300miles later I got the po161 code again. I'm really perplexed right now, I just may replace the cat system as thats all that left for thet system (i think), remember I already replced the 02 sensor and the code came back. I'm assuming it's noty the new sensor. Maybe replace the cat system. Any ideas left?? |

| I am wondering will things function without these o2 sensors. Is there a way around it somehow? | |

Morning all, I have a 03 tundra and when my shifter is placed in "drive" the little green light won't come on, but when i shift anywhere else all the rest of lghts work fine (reverse, park ect...) Anyone have this one happen before???? any guesses???

| I was told that on some Toyota vehicles that you have to replace the mass air flow sensor to realize the full benefit of a cold air intake system. Is this true? I am also curious as to the noise level of the Borla cat back system. I have decided to spend some money on my current Tundra to prevent the purchase of a new one. Thanks. | |
I have a 2004 toyota tundra I just bought and notice that when I start it up when cold I get a lot of blue smoke for a few minutes than goes away I had it check out at the dealer and they said everything was fine, I really don't like it, I did not notice this when I bought it two months ago, could it be the oil? its running standard 5-30 oil,they say no, some say use synthetic oil does this help? I only have 36000 miles on it, it does have a superchager and headers with daul exhaust from the factory. any info would help.
