I am replacing the tps sensor on my 2000 Toyota Tundra...my concern is that I will not not be able to get the adjustment correct as I don't believe it comes set to manufacturer specs. I am not p

Press the turtle? Could be many things, such as bad TPS, MAF, leak in hose between MAF and throttle body, vacuum leak, coolant temp sensor, bad catalytic converter or muffler. Any codes set?

First off I wasn't sure as to which engine you had in your vehicle as there is a 2.4 or a 3.3 liter engine for your vehicle for that year. I gave you some details on the 3.3 liter. I don't want to sound negative but Nissan's are basically dependant on its sensors which in turn send signals to the ECM which makes all of the adjustments as to how everything runs. If you do not have the proper equipment for diagnostic procedures it is difficult to get it correct but can be done. Even after you set the throttle position sensor (TPS) you need to reset the TPS idle position memory and then check the timing/idle mixture ratio and make any adjustments there if needed. I can do my best to try and walk you through it with details directly from the factory service manual and even can make you up a PDF of it if you want with ways to go around not having the diagnostic equipment. Also write if you have the 2.4 because the little bit of information I gave you below is only for the 3.3 liter engine. Again I'm not trying to sound negative to you and I believe I can walk you through it but it's not like just pulling a part & replacing it when it comes to your vehicle in order to get it done correctly.

Make sure it is a o2 malfunction before changing it,the o2 just gives information mainly,the generic code is a mass air flow sensor,and this would be more like what the problem is.

Hi. Please see procedure below:

Determine which alternator your Toyota Tundra will need. You'll want to be sure the new alternator is compatible with your Tundra's engine. Models built from 2000 to 2004 have a 3.4 L or 4.7 L engine. Models made from 2005 to 2006 offer options for a 4.0 L or 4.7 L engine. Starting in 2007, the Tundra is available with 4.0 L, 4.7 L and 5.7 L engines.

Disconnect the negative battery cable with a socket wrench. Remove the gravel shield if you need to access the alternator from under the car. Remove the electrical connector and unfasten the retaining nut on the alternator terminal with a socket wrench. This will allow you to remove the battery terminal wire.

Unfasten the lock nut, pivot bolt and adjusting bolt on the alternator with a socket wrench. Remove the drive belt and take the alternator off the vehicle.

Install the new alternator assembly. Use a torque wrench to tighten the lock nut to 25 ft. lbs. and the pivot bolt to 38 ft. lbs. Attach the adjusting bolt.

Connect the electrical harness and battery terminal wire to the alternator and fasten the retaining nut to the alternator terminal with a socket wrench. Install the gravel shield if you removed it. Replace the drive belt and restore it to the proper tension. Reconnect the negative battery cable with a socket wrench.

Thanks!

Throttle position sensor TPS is probably defective.
have the ECU scanned for codes and do the repairs the codes dictate.

This is all controlled by a computer, you are going to need to take it to a dealer, OR you can buy a tuner that will also control idle

For the 2000 model year there were several TSB ( technical service bulletins) issued concerning brakes on your vehicle. There were no recalls concerning brakes or brake failures however.
You can check the following web site and search information on the tundra recalls and TSB's for more detail.

Good luck.

This throttle body has a TPS ( throttle position sensor) and a Accelerator pedal sensor on it. The TPS is on the drivers side and the APS is on the pass side of the throttle body. When this happened your check engine lite came on then went off when it warmed up and acted normally. The code is still in History codes. Check it with a scan tool. I foget the code number but if it come up with the APS code in History, replace that sensor....not the TPS. It is a sealed sensor that gets moisture in it when the seal deteriates and it freezes in very cold weather.

You have to replace the sensor.it is located near the exhaust manifold.has the apperance of a sprk plug with a wire at the end.
