Dtc P2135: Throttle Position Sensor (Main / Sub) Voltage Correlation - Suzuki 2006 SX4 Service Manual

1A-160 Engine General Information and Diagnosis:
Step
9 Ground circuit check
1) Remove ECM from its bracket with ECM connectors
connected.
2) Check for proper connection of ECM connector at "E01-
51" terminal.
3) If OK, measure resistance between "E01-51" terminal of
ECM connector and engine ground.
Is resistance below 5
10 APP sensor assembly check
1) Check APP sensor (sub) referring to "Accelerator Pedal
Position (APP) Sensor Assembly Inspection in Section
1C".
Is output voltage within specified value?
