Good morning gentleman!

If you remember my problem (pasted below), finally I went to advance autoparts and thy tested with the scaner with the next result:

code Description
P0106 Manifold Absolute Pressure sensor (MAP)

P0137 O2 Sensor Circuit Low Voltage Bank 1 Sensor 2
P1491 Rad Fan Control Relay Circuit
P1496 5 Volt Supply Output Too Low


Any guide to locate the sensors in order to replace them my self will be very thankful.

Thanks for your support!!


Original post/problem:
________________________________________________-----------
2000 -T&C. 2 Big problems, please help Prob# 1:
-The RPM gauge goes almost 500 RPM and the computer (I think) try to compensate and accelerates almost over 2000 RPM, this happen a couple of times, but suddenly, the computer can not keep the RPM and fall lower than 500 and the engine turns off. When I accelerate with the pedal the RPM never get over 3500 RPM and starts to make a little cuts(this is wile parking).

- Some times the problem above happen while I´m driving and I losse power, with the acceleration pedal all the way down can not get more than 30 Mph. If I want to go faster I have to start pushing the pedal very quickly with out stop.
Some times the problem never happen and I can drive normally.

Prob# 2:
- The fans (2) in front of radiator do not work when I turn the A/C on and a few seconds after the little pressure valv over the A/C compressor start releasing the pressure an leaking the gas. This stops when I turn the A/C off. The fans work just fine when the engine is hot enough.

I called a mechanic and replaced the fuel pump and fuel filter but it did not solve the problem #1 I still have the problem.

For the problem #2 He replaced a little module, the one thar is below the fornt light near the radiator, and did not solve the problem. I paid him $450 and now his not answering his phone.

Can someone help me with an advice?

Thank for you support!!
