No. You follow air filter hose up to the intake.2 screws hold it to the side of the throttle body. Unplug the wire plug first.

My car won't accelerate properly no matter how hard you push on the gas. I got it up to 45 but thats as fast as I could get it to go. What could be wrong?


Hi and welcome to FixYa!

If that's the case then you definitely have a faulty TPS (throttle position sensor). If the TPS is faulty the result is a late response or unresponsive throttle. One good reason why it won't go. The TPS is connected on the throttle body. Have the TPS replaced and you'll be good.

Hope this helps and thank you for using FixYa! Have a good one!

My car has been stalling when I slow down. we were told it was my tps my husband is trying to put a new one on but cann not get the old off


Hi and welcome to FixYa!

You may need to give a little impact on the sides of the TPS to let it go off. The gasket may be holding it and a little impact can let it go.

What are the problems PO601 and PO121? how to solve them. thanks


121 is the throttle position sensor(TPS), 601 is control module memory error.(ECM,PCM)
I would replace the tps and erase the codes and go from there. If your getting crappy gas milage thi is because of the tps. It is located on the side of the throotle body. Opposite of the throotle cables. not hard to replace. Let me know

When I drive my 2000 monte ss in the summer after a while it will start shifting hard. I installed a trans cooler and it helped with the problem but it didnt cure it. I have heard about a pressure control...


Shift suddenly become very hard. When going from park to either reverse or drive it slams into gear. 1-2 and 2-3 shifts are also harsh. All gears seems to work. Problem may be intermittent: Check TPS for smooth electrical response. If the response is jumpy or erratic at all, replace TPS.

Start with checking your TPS and if that is good then it could be your EPC (electronic pressure control) solenoid. Easy fix in the pan.

Thank you for using Fixya and good luck.

When trans. is warm after extended driving the up shifts are very hard. This only happens during extended driving periods. Around town everything shifts fine.

Good luck Auto Zone or Parts Source has this part and can be replaced with in 20 min. Both parts store will have the step by step instructions and i believe the cost is around $65.00 for the TPS which is better then a transmission replacement.

P0121 code, 2000 chevy astro


Given that you have replaced the TPS and the PCM, the next step would be to check the connector itself and make sure it is making a good connection and there are no corrosion or anything like that on the connector.

After that, ensure that the TPS has the correct voltage to it, usually its around 5vdc, it should never have full batter voltage to it (12vdc). The PCM usually supplies both the 5vdc reference and the ground for the TPS. Its also entirely possible that (depending on where you bought the TPS) that you were given the wrong one for your vehicle. Not a common thing, but it could happen.

The code will be set if the PCM sees a TPS angle that is not consistent with the RPMs of the engine. If you are having any shifting issues such as hard shifts or the engine having to rev higher to shift, that usually a clear indication there is still something wrong with the TPS circuit even if the TPS itself is good.

Hope this helps.
