Weird Idle/TPS Issue with my Honda Accord EX 2003?Hi, im having this issue with my honda accord ex 2003, for some reason the car lighed the engine light on the dashboard, when we checked with the console to read the car computer it was saying TPS Pedal Position Low, so i replaced TPS but still having the same issue, is it the car computer(chip) having problems or damaged or is it something easy to get fixed, electrical?

computer failure rare,,,very rare check throttle body for sticking flapper.could be oxy sensor,,air flow sensor,,,temp sensor,

check voltage values for tps many are slightly adjustible. see service manual for voltage specs and adjustment. tps is typicaly 0-5v range with a perticular voltage at closed throttle (hot engine) use digital meter type only!! test incoming voltage supply and output voltage returning to cpu. If all incoming and outgoing voltages are correct carefully check all wiring and connectors for that circuit, test retur voltage at cpu if everything else checks out could be cpu (not likely!!).
