Citroen Berlingo III: engine stalls, difficult to restart

    Question: We service a 2009 1.6 HDi Citroen Berlingo III and recently replaced the crankshaft position (CKP) sensor as the cause of engine starting difficulties and hesitation on acceleration. The vehicle was OK for a while, but has now returned to the workshop with the same faults. There are trouble codes relating to the crankshaft position (CKP) sensor stored in the fault memory. We've tested the CKP sensor and it is not faulty. Can you help?
    Answer: Yes, we have come across these faults before on the Berlingo. The faults are due to a poor connection between the crankshaft position (CKP) sensor and the harness multi-plug. Cut the CKP sensor wiring harness a sufficient distance from the harness multi-plug and strip back the insulation (see figure 1.1). Disconnect the harness multi-plug from the CKP sensor and discard (see figure 1.2). Remove and discard the wiring harness guide (see figure 1.3). Using the repair kit, available from Citroen parts department, fit a modified harness multi-plug. Connect new harness multi-plug to CKP sensor (see figure 1.2). Fit new wiring harness guide (see figure 1.3). Ensure wiring harness secured correctly in area indicated (see figure 1.4). Carry out road test to ensure the fault has been rectified.
