Nonlinear(table) - When the main and backup signal are not linear in relation to each other and requires a custom table.Īll E-Throttle bodies connected to Max圎CU must be calibrated.Ĭalibrations are made in E-Throttle -> Throttle position.That means it can't calculate the fuel and air ratio. If the throttle position sensor fails, your ECU doesn't know how much air is passing through the valve. This helps your ECU control the fuel and air mixture. One of the leads is connected directly to the computer's 5-volt voltage supply, and the other lead connects to the ground circuit. Most have extra pins for extra functionality, such as cruise control traction and electronic stability control. Linear - When both main and backup signal are linear in relation to each other. The throttle position sensor (or TPS) monitors the throttle body butterfly valve. Throttle position sensors indicate the engine's throttle angle to the engine control module.Most mechanics will charge you under 500 to replace those. Check RealTime Data value: E-Throttle -> THROTTLE position sensor error. The throttle position sensor location on some cars is usually out in the open. Failing Throttle Position Sensor Symptoms. This placement allows the throttle position sensor to help the car’s electronic control unit (ECU) determine the correct air-to-fuel ratio as related to throttle input. The max allowed error between main and backup position allowed. Most throttle position sensors are located between the car’s air intake and throttle body. Voltage input(backup) from throttle when throttle is fully "open". Voltage input(backup) from throttle when throttle is fully "closed". Voltage input (main) from throttle when throttle is fully "open". Voltage input (main) from throttle when throttle is fully "closed". ![]() When E-Throttle is activated in Max圎CU, the RealTime Data value: TPS is actually the pedal position. 5286 - Throttle Position Sensor (G69) P0121 00 237 - Implausible Signal MIL ON - Confirmed - Tested Since Memory Clear Freeze Frame: Fault Status: 00000001 Fault Priority: 2 Fault Frequency: 18 Mileage: 299548 km Date: 2036.14.07 Time: 16:49:59 Engine speed: 161.00 /min Normed load value: 100. In newer versions, the TPS analog input wire can be used as "other 0-5v functions". Note: Inputs from TPS input (CMC1:G2) was completely discarded in MTune versions before 1.108 (when E-Throttle was activated).
