Bosch Accelerator pedal position sensor

General Information

Bosch PWG-3 from a Honda Jazz

The trade name for this sensor is Bosch PWG-3, this is quite ubiquitous and used by several manufacturers over decades

In the early days of electronic diesel control, many cars were adapted to use e-throttle sensors from the standard cable throttle pedal, as the gasoline versions were still using cable throttle. Being that Bosch ECU's powered a lot of these cars its not surprising to find a bosch sensor to do what you need. Of course it makes sense to find one thats common in your region.

The voltage from both sensors ramps linearly from the fully released position to the fully depressed position. The pedal should be supplied with a reasonable stable and accurate 5V supply to ensure a proper readout.

Voltage Output of Throttle Sensors

Pedal Position	Sensor 1	Sensor 2
Fully Released	2,47 V	0,56 V
Fully Depressed	3,74 V	1,92 V

Versions

The colors and pinout of wiring varies depending on manufacturer.

When looking for a dual potentiometer sensor, be sure to obtain a SIX-wire sensor. There are variants of this with five wires, they have only ONE potentiometer and a position switch. This list is non-exhaustive, but demonstrates the availability of the sensor
