p0133 advice/?

[Tucson Mike]

For the last couple of months I've been getting the TPS code showing up and then going away. About a month ago, I cleaned the TB and MAF and then last week I took the TB off and replaced the TBS with a genuine Toyota part and took the IAC off and cleaned that as well. On the way to work sure enough the check engine light came on. Checked the codes and this time it was the TPS p0120 and the p0133, WTH? Cleared the codes and of course after about 40miles check engine light came on again, but this time it was only the p0133 (02 sensor). Here's my ? Prior to doing the work I did remove the EFI relay as well.

1) Is this a coincident that the p0133 came on, or could I have done something to affect it by changing out the tps and taking the TB off? I did replace everything with Toyota gaskets and parts

2) I have a v-6 with 160,000 miles (bought it at 30k) and have never replaced anything until now. I've read that it would be a good idea to replace o2 when they are getting up there in miles.

3) Anything else I can check. I hate to throw money at it if I'm not positive that's the problem.


Thanks for your suggestions.

You are pretty neglectful if you've never replaced anything.

Basic maintenance calls for a good amount of work to be done right now.

You should do the maintenance or sell it for cheap like $2k.

- fuel filter
- plugs
- wires
- 02 sensors
- LBJs
- radiator

That is a good start. Btw use only OEM (eg real Toyota) parts. Don't put Bosch, NAPA, Moog, AutoZone ect in your 4Runner becAuse You will regret doing so.

Btw, I will add that your thread is funny because it basically reads:
"I have never done maintenance in over X years and 130,000 miles. Now my truck is broken. Please help"

Find a good mechanic. Make sure he uses real Toyota parts. Replace the above items. Also the timing belt and water pump would be a good idea.
