Dtc P2135: Throttle Position Sensor (Main / Sub) Voltage Correlation - Suzuki Grand Vitara 2011 Manual

Step
9 Ground circuit check
1) Remove ECM from its bracket with ECM connectors
connected.
2) Check for proper connection of ECM connector at "E23-
51" terminal.
3) If OK, measure resistance between "E23-51" terminal of
ECM connector and engine ground.
Is resistance below 3
10 Accelerator pedal position (APP) sensor assembly
check
1) Check accelerator pedal position sensor (sub) referring
to "Accelerator Pedal Position (APP) Sensor Assembly
Inspection: For Petrol Engine Model in Section 1C".
Is output voltage within specified value?
