Note: An accelerator cable of Fiat Punto is only used on SOHC (8-valve) engines. On DOHC (16-valve) engines, a 'drive-by-wire' system is employed, whereby the throttle valve is operated by a throttle valve actuator incorporated in the throttle body. The system is controlled by the engine management ECU using signal inputs from the accelerator pedal potentiometer.

Removal the accelerator cable of Fiat Punto

1 Remove the air cleaner assembly.
2 Disengage the inner cable from the throttle cam, and withdraw the outer cable from the rubber grommet on the mounting bracket (see illustrations).

3 Working back along the length of the cable, free it from any retaining clips or ties, noting its correct routing.
4 From under the facia, inside the car, unhook the cable from the fork at the top of the pedal arm.
5 Release the bulkhead grommet and withdraw the accelerator cable from inside the engine compartment.

Refitting the accelerator cable of Fiat Punto

6 Feed the accelerator cable through the bulkhead grommet, then return to the car and locate the inner cable end fitting in the pedal arm.
7 From within the engine compartment, work along the cable, securing it in position with the retaining clips and ties, and ensuring that the cable is correctly routed.
S Pass the outer cable through its throttle body mounting bracket grommet, and reconnect the inner cable to the throttle cam. Adjust the cable as described below.

9 Extract the retaining clip from its groove in the outer cable (see illustration).

10 Ensuring that the throttle cam is fully against its stop, gently pull the cable out of its grommet until all free play is removed from the inner cable.
11 With the cable held in this position, refit the retaining clip to the last exposed outer cable groove in front of the rubber grommet. When the clip is refitted and the outer cable is released, there should be only a small amount of free play in the inner cable.
12 Have an assistant depress the accelerator pedal, and check that the throttle cam opens fully and returns smoothly to its stop.
13 On completion, refit the air cleaner assembly.
