Sensors?

[chingon77]

I read the codes and the following popped up as a malfunction:P0325 Knock sensorP0120 TPS/Pedal positionP0443 Evap EmissionP0732 Gear 2 ratio incorrectP0733 Gear 3 ratio incorrectP1705 Malfunction system specific

From the manual it seems as though a malfunction in the TPS/Pedal Position P0120 will cause the the P0732,P0733, P1705 to malfunction.Is there anything i can do/try/troubleshoot before I start replacing sensors?thanks

anyone?

I would clear all the code and run the car for a few days, and read the code again. But most importantly, how does the car run?

Sorry I fogot to mention how the car ran. Well there is definatly something funky going on. Sometimes when i'm driving the car will suddenly decelrate and accerlate and the gears shift back and forth. My dad cleared the codes a couple of weeks ago but that time only the knock sensor and 1 other sensor i forgot was showing up. This time the shift sensor with 3 other related sensors appeared.

Since you have a FSM, then follow the manual to do a output voltage test on the TPS. Bad TPS going bad is not uncommon on our cars, at least that is what i heard. There is also a test for the knock sensor, too. You have voltmeter, right?

I downloaded the manual somewere online the other day. Yes we have a voltmeter.

well i checked out the volts for the sensor and the harness and it checked out fine. The volts were the way they were supposed to be. So we cleaned the air intake valves because they were kind of dirty. So i'll drive it around and see if the tps code pops up again. I also found a harness on the backside, left engine compartment next to the strut that wasn't pluged in correctly. So i'll see what happens after driving it around.
