I think there is something wrong with my throttle position sensor, the ECU says so, and I am wondering what it needs to be fixed. Do i need a new one, or is it easy to fix? thanks

 

tps's are a pain in the ***. pull off the connector that goes to it and measure the voltage from the sensor w/ a multimeter while car is running. should be aprox 5V. if it is damn close to that clear the ecu and forget about it. USDM hondas are gay as **** w/ the tps. their rivated on. JDM and EDM are all screwed in. only real way to change them on USDM tbodys is to drill out the rivets get a new sensor or use old on and screw it back in. they have to be set by voltage tho 5V at idle

First off, there are no rivets on the TP sensors.
those are break away screws (10-32 thread) that the head pops off as soon as they are torqued.
you can remove them by using a fine flat head screw driver and taping with a hammer on the side of the washer in a counter clock wise direction.
you can also use a dremmel tool with a cutting disk to cut a groove on the head
and then use a flat head screwdriver to remove the screw.
About the problem with the TPS.
If you have used a throttle body spray cleaner, chances are the TPS might be damaged.
I use a spare TPS plug with about 6 inches of wire on it to check the sensor.
you need a tester and you need to chek for resistance (Ohms)
With the Throttle body in the closed position it should read .5 volts
With the throttle body on full open it should read 4.5 volts.
The important one is the .5 volts at idle.
If it's lower or higher the ECU will throw a code.
You can adjust it by loosening the crews and rotating the TPS very slowly until you get .5 volts at ilde.
I have fixed a few TPS that were throwing ECU codes.
