Throttle / pedal position sensor / switch "A"
Hint:
These dtcs relate to the throttle position (tp) sensor.
Description
The tp sensor is mounted on the throttle body, and detects the opening angle
of the throttle valve. This
sensor is a non-contact type. It uses hall-effect elements in order to yield
accurate signals even in
extrem ...
