Beggernator: Added revised pinout for UK model sensors.

=General Information=

[[File:Honda accelerator pedal sensor 01.jpg|thumb|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.

[[File:Connector pinout.jpg|thumb|Honda accelerator pedal sensor connector pinout<ref>Forum Reference: https://openinverter.org/forum/viewtopic.php?p=66006#p66006</ref>]]

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

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.

(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)

Beggernator: confirmed resolver pole count

These motors are designed as a belt driven starter/generator for Kia and Hyundai's hybrid vehicles. They have a water jacket (stator and rotor etc remain dry), poly-v pulley and provision for a bolt on belt tensioner.

== Details ==

|-
|'''Pole pairs'''

|-
|'''Mechanical output'''

|}

== Pinout ==
The large connector is the three phases. These can be used with the factory connector (part number <?>), or by removing the two covers (JIS screws) and connector (4x 10mm hex head screws externally, plus 3x 4mm hex 'allen' head screws on the internal phase connectors) the three phase connections become available using 6mm ring terminals.

The 10 pin Econoseal connector includes the resolver connections, temperature sensor connections and two shield connections (connected to case internally)
