Code No. P1704, P1703, P1702 throttle position sensor system

Probable cause

If the TPS output voltage is 4.8 V or higher when the engine is idling, the output is judged to be too high and diagnostic trouble code No.P1704 is output. If the TPS output voltage is 0.2 V or lower at times other than when the engine is idling, the output is judged to be too low and diagnostic trouble code No.P1703 is output. If the TPS output voltage is 0.2 V or lower or if it is 1.2 V or higher when the engine is idling, the TPS adjustment is judged to be incorrect and diagnostic trouble code No.P1702 is output.

o Malfunction of the throttle position sensor

o Malfunction of connector

o Malfunction of the TCM
