Editing Throttle Position Sensor (section)

===My Method===

(This is OK for a manual car, but probably not for an auto, as the pot position is critical for the auto operation.)

*1) Loosen TPS retaining bolts, and start engine.  Let engine idle, leave throttle in idle position.

*2) Move TPS fully clockwise, engine will idle like shit.

*3) Turn TPS anti-clockwise slowly until engine idles properly (i.e. switch is closed).  Turn TPS a tad further, then nip up the retaining bolts, and done.  (Do not lean on the bolts, as they are tiny, and they're going into aluminium, not steel.)

*'''Note:''' If the idle doesn't improve when the TPS is fully anti-clockwise, disconnect the plug, and short the top two sockets on the plug with a piece of wire or needle nose pliers etc.  If the idle improves when you do this, then the TPS is faulty.  Conversely if the idle still doesn't vary, the wiring to the sensor may be faulty, or a problem exists with the idle control gear (different subject), or something else again.
