J. jjp · No codes or service throttle lights at all. Just the intermittent problem with the cruise control for several months now, and the loss of any response to the pedal four or five times this morning. The van had sat unused for about twelve days until this. The accelerator pedal position sensor then sends an electronic signal back to the ECM. The ECM calculates the signal and commands the throttle body to open for the engine to consume more fuel. Accelerator pedal position sensors fail prematurely from wearing out or exposure to wet and cold conditions from winter driving

There are 2 sensors in the accelerator pedal, both should increase in the same direction as the accelerator is pressed but they have different scales. This means one counts from 0 to 100, while the other one counts from 0 to 50. Accelerator Position Sensor faults can be caused by issues with the Oxygen Sensor(s) and it's wiring With the sensor, there come the accelerator pedal position sensor problems as well. The sensor as the name implies works to adjust with the pressure applied on the accelerator paddle. It works along with the varying amount of depression made on the gas pedal by the driver. This ensures the fuel-air mixture ratio and sends it accordingly to the. The accelerator pedal position (%) isn't the position of the floor pedal in these drive-by-wire systems. Rather, it seems to be a virtual pedal; a construct within the ECM. This becomes apparent when observing the pedal position and throttle position sensor data, which don't always correlate with the floor pedal itself The manual says the acceptable range is .75v to 4.1v for No.1 sensor, .38v to 2.05v for the No.2 sensor. Max voltage is 4.9 from terminal E on the sensor, at which point the code is triggered. If you can locate a service manual there is a complete diagnostic tree for this code. Usually the result is a new throttle pedal
