156 1.6tsparx throttle potentiometer help!!

Could anyone enlighten me on the throttle potentiometer, is it the same thing the same as the throttle position sensor? Also where is it? Is it part of the throttle body? thanks in advance!!

First thing - what year is your 156 - the earlier ones (CF2, upto 2000-ish) didn't have a throttle pot - the throttle flap was cable operated, although there is an idle control valve bolted onto the rear of the throttle body which (surprisingly enough) maintains the idle speed. If your car does have the later so-called fly-by-wire throttle, there are two compnents - the throttle potentiometer bolted near to the throttle pedal, and linked to it by a bell-crank, and the actuator which is bolted on the throttle body. Problems with either of these are often down to the connector plugs in the wiring....

Hope that helps.
