TPS censor problem help please
ok im start like this my prelude is a 1995 obd1 h22a1 and i been having problems with my tps censor i replace it yesterday but after i replace it check engine light come up and i try to reset the computer disconnecting the battery but didn't work so i know i know read the code is the next step but i dont know how if some one have any idea please let me know or if some one know how to fix the problem let me know please thank you everyone i been checking the hold day for it!!!!
First it's spelled Sensor.
Second i would list the symptoms before you replaced the sensor and the current symptoms.
To check the CEL (Check Engine Light) there is a connector behind the ash tray on the driver's side which you can get to from where your legs normally go.
with the car off jump the connector (using a wirer or paper clip to complete the loop)
then turn the car key to the second settings (don't start it)
then count the blinks of the CEL on the dash.
three short blinks would be a code 3
one long blink followed by three short blinks would be 13
then search for the code or post the results and go from there

you need to calibrate the tps with a multimeter. should be .5v closed, 4.5v @ wot.
You need to connect a multimeter to the tps and move the sensor around until the correct ohm specs are achieved.
With the TB closed, sensor disconnected, ign off:
Pins 1 and 2 = 0.5-0.9ohms
Pins 2 and 3 = 3.6-5.4ohms
You also need to be sure you have correct voltage, sensor connected, ign 'on':
Pins 1 and 3
0.5volts with the TB closed
4.5volts with the TB fully open
These specs should also be correct from the factory. If theyre not, and you havent replaced the tps, you know its time to do so.
If you have replaced the tps and these readings arent met, your sensor isnt positioned properly
