throttle position sensor installation - 04/16/06 10:28 PM
I just recently a SVT tb on my SE and I ended up getting a code P1120, tps sensor voltage to low, it turns out that I had a SE tps and not a SVT one. Also I have read alot that people have been having trouble getting the correct tps.
Here is a SE throttle body with out the tps
The SE tb turns clockwise where the SVT tb turns counterclockwise as viewed from the front of the vehicle. The SVT tb will look somewhat similar.
When purchacing a tps it is a good idea to check the direction that the sensor turns. As I noted before the SE tb turns clockwise and the SVT tb turns counterclockwise. When you view the tps you will be looking at the opposite side of the sensor then you would see as it is installed on the vehicle.
When you purchase a tps for a SE the tps needs to turn counterclockwise and the SVT tps needs to turn clockwise, remember this is 180 degrees from how it is viewed on the car, reference this photo.
what also needs to be know is that the tps does not drop right onto the tb, it needs to be loaded, ie the sensor needs to be slightly turned when teh tb is closed. The sensor reads from about 0.1 volts to 1 volts for closed to open positions. The following photos show how the tps should be installed on a SE tb, if you don't install it correctly you will break the sensor.
now turn the sensor so that the mounting holes line up and bolt it down, you need to turn the sensor counterclockwise
The SVT tps is installed the same way but the sensor needs to be offset upwards and then rotated clockwise to be mounted.
hope that helps some people that have getten the wrong sensor or have had trouble installing a tps
