85 Disconnect the wiring plug from the sensor, and connect the leads of an ohmmeter to the sensor terminals.

86 Measure the resistance of the sensor and compare the readings obtained with those given in the Specifications at the start of this Chapter.

87 Disconnect the sensor wiring plug, and unclip it from the bracket adjacent to the oil level dipstick (see illustration).

88 Remove the auxiliary drivebelt(s) as described in Chapter 1.

89 Remove the crankshaft pulley and timing belt covers as described in Chapter 2A.

90 Undo the bolt and remove the sensor from the mounting bracket (see illustration).

91 Refitting is a reversal of removal. Tighten the sensor bolt to the specified torque.

92 Remove the alternator as described in Chapter 5A.

93 The sensor is located adjacent to the crankshaft pulley at the front of the engine. Trace the wiring back from the sensor and disconnect the wiring plug (see illustration).

94 Connect the leads of an ohmmeter to the sensor terminals, and measure the resistance

start of this Chapter.

95 Proceed as described in paragraphs 92 and 93

96 Undo the bolt securing the sensor wiring loom retaining bracket to the engine block.

97 Undo the retaining bolt and withdraw the sensor from position (see illustration). Discard the sensor O-ring seal, a new one must be fitted.

98 Insert the sensor into position, with a new O-ring seal.

99 Tighten the retaining bolt to the specified torque, and reconnect the wiring plug.
