halves
3 Bend back the locktabs and unscrew the two sensor retaining bolts (see illustration).
27.3 Unscrewing the throttle position sensor retaining bolts
Withdraw the locking plate and sensor from the throttle shaft.
4 Refitting is a reverse of removal, ensuring that the moulded side of the sensor faces towards the inlet manifold. The flat on the sensor wiper engages with the flat on the throttle shaft.
2.0 litre DOHC models
5 Disconnect the battery negative lead.
6 Free the throttle position sensor wiring plug from the retaining clip located on the underside of the throttle body. Disconnect the wiring plug halves by releasing the locktabs and pulling on the plug halves (see illustration).
27.6 Throttle position sensor (A) and wiring plug (B)
7 Unscrew the two sensor securing screws, and withdraw the sensor from the throttle shaft.
8 Refitting is a reversal of removal, noting that the sensor fits with the wiring at the bottom.
Ensure that the sensor actuating arm engages correctly with the throttle spindle.
