Throttle position sensor on 1994 Toyota Corolla

Check Engine light is on. The code says that it is the throttle position sensor (TPS). Is there something besides replacing the TPS that might fix the problem. If not, how difficult is it to replace? Thanks

The code indicates the throttle position sensor is bad and the code is usually right, but it could be a wiring issue or less likely a computer issue. There is a specific test for the sensor checking for power and signal value and then a procedure for setting the switch using an OHM meter to set the switch at its correct position. Switch its self is easy to replace. There is a company that independent auto repair shops "buy" their information from that offer a very reasonable service to do it yourselvers. You can get a one week subrcription or year subscription very cheap. The information is year make and model specific repair procedures, service bulletins, component locations, wiring diagrams ect.... great quality information same as the professionals have ,much better than generic workshop manuals from parts stores, much cheaper than the factory manual try http://bit.ly/mitchell_repair_manuals_online and get an online repair manual subscription.
