Po121 means that there is a problem with the throttle position sensor ( tps). or in the wiring or connector, most likely its the tps that is bad. first remove connection from tps, heres how to test. use an ohms meter and hook a lead to top or bottom terminal of tps. use other probe on center terminal of tps. move throttle plate slowly, if the needle on meter does not move at a smooth pace, then tps is bad. good-luck!!
