1. DTC

description:

DTC P2135

Related fault of Electric throttle valve position sensor1# . 2#

ECM compares TPS1 and TPS2 input signals. Two input signals' sum at any time should be close
to 5V. If ECM detects difference between the sum of TPS1 and TPS2 signals and the theoretical
value is big, ECM will report the DTCs code.
