Ignition HT coil - removal, testing and refittingIgnition system / Ignition HT coil - removal, testing and refitting
Note: On models with static distributorless ignition systems, the ignition HT coil is an integral part of the ignition module. Refer to Section 6 for removal and refitting procedures.
All engines except TU series 1 The ignition HT coil is located at the lefthand side of the engine compartment mounted on the side of the suspension strut tower.
2 Disconnect the battery negative lead.
3 Slide the cover off the coil and adjacent ignition module (see illustration).
3.3 On all engines except TU series, access to the coil and ignition module is gained after sliding up the protective cover
4 Disconnect the wiring at the coil LT terminals, and the HT lead at the coil centre terminal.
5 Release the coil mounting clamp and remove the coil.
TU series engines
6 The ignition HT coil is mounted on the lefthand end of the cylinder head, above the distributor.
7 Disconnect the battery negative lead.
8 Refer to the relevant Part of Chapter 4 and remove the air cleaner assembly. Once the air cleaner is removed, move aside any pipes, hoses or wiring as necessary for improved access.
9 Where applicable, disconnect the wiring connector from the capacitor mounted on the coil mounting bracket and release the TDC sensor wiring connector from the bracket.
10 Disconnect the HT lead from the coil then depress the retaining clip and disconnect the coil wiring connector (see illustration).
3.10 Disconnecting the coil wiring connector (arrowed) on TU series engines
11 Slacken and remove the two retaining bolts and remove the coil and mounting bracket from the cylinder head. Where necessary, slacken and remove the four screws and nuts and separate the HT coil and mounting bracket.
12 Testing of the coil consists of using a multimeter set to its resistance function, to check the primary (LT “+’“ to “-” terminals) and secondary (LT “+” to HT lead terminal) windings for continuity, bearing in mind that on the four output, static type HT coil there are two sets of each windings. Compare the results obtained to those given in the Specifications at the start of this Chapter. Note the resistance of the coil windings will vary slightly according to the coil temperature, the results in the Specifications are approximate values for when the coil is at 20°C.
13 Check that there is no continuity between the HT lead terminal and the coil body/mounting bracket.
14 If the coil is thought to be faulty, have your findings confirmed by a Peugeot dealer before renewing the coil.
Refitting (all models)
15 Refitting is a reversal of the relevant removal procedure ensuring that the wiring connectors are securely reconnected and, where necessary, the HT leads are correctly connected.
