Check engine Got a code 63. Now, how do I check the throttle position circuit to find the exact problem?

first code it's P0320 Possible causes
- Faulty Ignition/Distributor engine speed sensor
- Faulty Crankshaft Position sensor
- Ignition/Distributor engine speed sensor harness is open or shorted
- Ignition/Distributor engine speed sensor circuit poor electrical connection
- Low battery charge
- Faulty Engine Control Module (ECM)

You are propably going to want to have the TCM(trans,control module)scanned as its possible your scanner is only doing the engine codes.let me know if you need some direction as what to check and do ok?

31 canister or egr valve control system,63 throttle position sensor or circuit,for egr inspect visually hoses elect. plug at egr solenoids after that you might want to buy a repair manual because theres quite a few test to do.for tps check unplug connector at sensor connect 1probe of dig.ohmmeter to center terminal the other on either side move throttle slowly,resistance should vary slowly,if its erratic or none change tps ,voltage at plug not sure,think its 5vlt
