This document must not be used in any way, such as copying and redistributing to third parties, without our consent Visually check sensor; Replace sensor if damaged. Trouble Shooting: Step Checks IF YES IF NO 1. Is there any rust/oxidization observed on Sensor Terminals Clean the Rust or repair or replace Go to Step 2 2. Is there wiring harness electrical continuity between ECU pins B60, B36, B19&Accelerator pedal Sensor connector pins 6,1,5. Go to Step 3 Establish continuity by rectifying harness connections as per the circuit schematic 3. Are there any pins damaged at Sensor/EMS ECU Connector Replace the connector or wiring harness Go to step 4 4 Are there any pins backed out from the Sensor/EMS ECU Connector Rectify/Replace Connectors Go to Step 5 5 Is Sensor Supply Pin B36 Short circuited to Battery/GND or open? Repair the harness as per the schematic Go to step 6 6 Is Sensor Signal Pin B60 Short circuited to battery/GND or open circuited? Repair the harness as per the schematic Go to Step 7 7 Is sensor physically Damaged Replace Sensor Go to Step 8 8 Fault Still Persists? Replcae Sensor and then Fault still persists then Call Hot Line Follow the steps again for reconfirmation DTC’s confirmation (checks before handing over vehicle to customer):- After rectification, ensure the following points by referring engine parameters using TML diagnostic tool before handing over to customer - Accelerator pedal is not pressed - Pedal position in diagnostic tool should be less than 5%. Accelerator pedal is fully pressed - Pedal position in diagnostic tool should be more than 95 % Drive the vehicle on road to feel the accelerator pedal response in different vehicle speed & in different gear conditions
