Manifold pressure sensor
41. The manifold pressure sensor is mounted on the front of the intake manifold.
42. Disconnect the ground cable from the battery (see "Disconnecting the battery").
43. Disconnect the electrical connector, then remove the screw and remove the sensor from the manifold (figure 13.43).
Figure 13.43. Disconnect the manifold pressure sensor electrical connector (1), and then remove the screw (2) (the model shown is one with a 1.4L engine)
44. Installation is carried out in the reverse order of removal. Make sure the sensor seal is in good condition.
Coolant temperature sensor
45. The coolant temperature sensor is screwed into the coolant distribution housing on the left end of the cylinder head. For detailed installation and removal information, please refer to chapter 3.
Air intake temperature sensor
Note: On 1.4L engine models with the Sagem S2000 system and all 7.6L engine models, the air intake temperature sensor is an integral part of the throttle body and cannot be removed.
46. The air intake temperature sensor is installed on the base of the throttle body. On early models, the sensor screws into a threaded hole on the underside of the throttle body, while on later models it is held in place with clips.
47. Disconnect the ground cable from the battery (see "Disconnecting the battery"), then disconnect the sensor electrical connector (figure 13.47).
Figure 13.47. Disconnect the electrical connector...
48. Unscrew the sensor or release the clamps and release the sensor from the throttle body (figure 13.48).
Figure 13.48. ...then release the air intake temperature sensor from the clamp on the throttle body (models with a 1.4 L engine)
Tip: The air intake temperature sensor clamps can be released by passing a tight-fitting open-end wrench over the end of the sensor.
49. Installation is carried out in the reverse order of removal. Make sure the sensor seal is in good condition.
Crankshaft sensor
50. The crankshaft sensor is located on the front side of the clutch housing.
51. Disconnect the ground cable from the battery (see "Disconnecting the battery").
52. Disconnect the sensor electrical connector and release the wiring. Unscrew the bolt and remove the sensor assembly with the bracket from the gearbox (figure 13.52, a, b).
Figure 13.52, a. Disconnect the electrical connector and remove the screw (marked with an arrow)...

53. Installation is carried out in the reverse order of removal.
Throttle body heating element
Note: The heating element is only used on the aluminum throttle body. For a plastic case, a heating element is not needed.
54. The heating element is located on the top of the throttle body.
55. Disconnect the ground cable from the battery (see "Disconnecting the battery").
56. Disconnect the electrical connector, then remove the screw and the heating element from the throttle body (figure 13.56, a, b).
Figure 13.56, a. Disconnect the electrical connector and then remove the screw (marked with an arrow)...
Figure 13.56, b....and remove the heating element from the throttle body (models with a 1.4 L engine)
57. Installation is carried out in the reverse order of removal.
Vehicle speed sensor
58. The vehicle speed sensor is an integral part of the speedometer. For detailed installation and removal information, please refer to chapter 7.
Knock sensor
59. The knock sensor is screwed into the rear of the cylinder block. For detailed installation and removal information, please refer to chapter 5B.
Inertia fuel supply switch
60. The inertial fuel supply switch is located in the right rear corner of the engine compartment.
61. Disconnect the ground cable from the battery (see "Disconnecting the battery").
62. Cut the clamp (if applicable), then unscrew the nuts and remove the switch from the vehicle, disconnecting the corresponding electrical connector.
63. Installation is performed in the reverse order of removal. Finally, reset the switch by pressing the top button.
Camshaft position sensor
Note: The camshaft position sensor is only available on 1.4L engine models with the Motronic MP7.3 system.
64. The camshaft position sensor is located on the rear of the coolant distribution housing at the left end of the cylinder head.
65. Disconnect the ground cable from the battery (see "Disconnecting the battery").
66. Disconnect the electrical connector, then unscrew the bolt and remove the sensor from the housing.
67. Installation is performed in the reverse order of removal. Make sure the sensor seal is in good condition.
Body accelerometer
Note: The accelerometer is only available on models with a 7.4L engine and the Motronic MP7.3 system.
68. The body accelerometer is located in the engine compartment. To remove it, first disconnect the ground cable from the battery (see "Disconnecting the battery").
69. Disconnect the electrical connector, then remove the bolt and remove the sensor from the vehicle.
70. Installation is performed in the reverse order of removal.
Electric motor of the throttle actuating device
71. The throttle actuator motor is fitted to 1.4L models with the Sagem S2000 system and all 1.6L models. It is integrated into the throttle body and is not supplied separately.
Accelerator pedal position sensor
Note: The accelerator pedal position sensor is only available on 14L engine models with the Sagem S2000 system and all 7.6L engine models.
72. The accelerator pedal position sensor is located above the right engine/gearbox mount (figure 13.72).
Figure 13.72. Location of the accelerator pedal position sensor (marked with an arrow)
73. Disconnect the ground cable from the battery (see "Disconnecting the battery"), and then disconnect the pedal position sensor electrical connector.
74. Disconnect the accelerator cable from the accelerator pedal position sensor cam, and then pull the cable housing out of the rubber bushing of the support bracket. Remove the spring clip from the cable housing.
75. Remove the two support bracket mounting bolts and remove the pedal position sensor and support bracket from the engine compartment.
76. Unscrew the two nuts and unscrew the bolts securing the sensor to the support bracket and separate these elements from each other.
77. Installation is performed in the reverse order of removal. Finally, adjust the accelerator cable as described in paragraph 3.
