1995 Toyota T100 Q&A
1995 Toyota T100 Question: OBDII or NOT
Ok guys, I usually answer questions but I am stumped on what I got here. Just bought this truck, manufactured 09/94, says meets Calif. emissions for year 1995 but this has both the E1/TE1 diagnostic code setup under the hood so can count code blips and also has OBDII diag link under the dash. Has CEL on but runs fine. Was able to pull two codes, P0420 and P0510 for oxygen sensor prob and TPS prob, I attached my scanner and retrieved them and then cleared and will drive to see if come back. I recently fixed broken crossover pipe between EGR housing and back of exhaust manifold. This truck starts right up, idles high till goes into closed loop, runs fine with no misses and no power problems. What do I have here? If the codes come back I will do diag and report back. Thanks in advance. Always owned Chevy's and Harley's so not used to working on it as I have ran shops for years and haven't done much wrenching except at home. - raiderron
You need to check the data on your scanner if it reads data. If not, use a meter and see if the O2 sensor and TPS are good or not. Then you'll know what you're dealing with. - Superbob
For starters, all T100 trucks were made in japan then sent to America to see if the demand for Toyota's attempt to enter the full size truck growth. In 1995 America bought the rights from Japan for the full size truck, but when they started production the T100 name changed to Tundra to represent that it was American made. Now, the reason that the 1995 and up T100's have the E1/TE1 plugs under the hood is for other testing and modification purposes. One use for these plugs under the hood that I've found out from Toyota is for converses to duel fuel systems like the FlexFuel cars and trucks. If you need anything else you can get ahold of me on this site - Lil G
As I last stated in my original post about this new rig to me I cleared codes and have not come back. What is confusing is that has OBDII connector under dash and also has diag link box for TE1 and...
About 2 weeks ago I took my 95 Toyota T-100 into a local Toyota dealer for an oil leak in the valve cover gaskets. They cleaned the whole top end of the engine (intake manifold removed and cleaned ...
