DTC

P2135

Electronic Throttle Position Sensor 1 and 2 Circuits Relations Malfunctions

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.
