Honda Accelerator pedal sensor

General Information

A better image would be nice, but this is what the sensor looks like

The original cable is shielded to avoid interference from other sources and resulting unwanted acceleration or deceleration.

Honda accelerator pedal sensor connector pinout

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 (P/N 37971-RCA-A01)

Pedal Position	Sensor 1	Sensor 2
Fully Released	0.05 V	4.30 V
Fully Depressed	0.10 V	4.90 V

UK spec versions have different pinout.

When connected correctly sensor 1 is half the scale of sensor 2, fully pressed yielded max values of 1432 for Pot1 and 2980 for Pot2 on a v3 mini mainboard.

Connector Pin	A	B	C	D	E	F
Function	5V REF 1	GND 1	SIG 1	SIG 2	5V REF 2	GND 2

(In OEM application pins E and F are swapped, giving SIG 2 an inverted output, this isn't compatible with open inverter so a pin swap is needed)
