What are the causes of rationality failure between throttle pedal signal 1 and 2?
1 Answers
According to fault phenomenon analysis, unresponsive throttle is caused by fault code P213564 indicating rationality failure between throttle pedal 1 and throttle pedal 2 signals. Below are relevant details: 1. Data reading: Analyzed engine data stream and compared voltage differences between throttle pedal 1 signal and throttle pedal 2 signal, finding both signals at normal voltage levels. 2. Accelerator pedal: Throttle pedal 1 signal voltage measured 0.8V while throttle pedal 2 signal showed 0.4V - maintaining normal proportional relationship, yet ECU persistently reports undeletable fault code. 3. Throttle operation: Both signals demonstrate synchronized proportional changes during pedal operation, but the fault code remains undeletable. Since undeletable fault codes prevent vehicle delivery to customers, thorough investigation of this fault point is required.
