The ignition light on my car is constantly on and the fault code came up throttle switch full load contact, throttle switch not running I have checked the wiring loom and it is ok, My car has no AIR unit on it would this cause the fault? Also the throttle switch on my engine does not click but when I went to replace it I was told that it should'nt click anyway is this then a pontimeter??
If so would having a potimeter instead of a switch cause this fault or are the two interchangable???
If its a C20XE, its a microswitch TPS, ie you can hear it 'click'
C20LET engines use a smooth pot TPS, so you can't hear it click.
Clean the contact pins with contact spary, check the plug fits home, and that cable form is from from splts and cuts etc. If you have a DVM you can measure the resistance between the pins while you move the butterfly flap open and close.
