Autodata Technical Issue 25 – Intermittent starting and running problems on 2009 Peugeot 308
Each month the Autodata team answers a common technical question and provides a printable document with technical diagrams to download and keep, exclusively for IGA members. This month a Peugeot 308 repeatedly shows camshaft position sensor fault codes alongwith running and starting issues.
Q. We have a 2009 Peugeot 308 1.6 VTi in the workshop with an intermittent starting and running problem. We can’t get the car to play up but several camshaft position sensor fault codes P0341, P0342 and P0343 were present. We have checked the camshaft position sensor and deleted the fault codes but the customer keeps returning the car with the same symptoms and the same fault codes are present. Can you shed any light on the problem?
A. The problem your customer is experiencing is probably due to a known problem with the inlet camshaft position (CMP) sensor multi-plug, it also affects other models fitted with this family of engines. Water ingress into the inlet CMP sensor multi-plug is causing corrosion.
Check the CMP sensor and multi-plug for corrosion. If necessary, replace the CMP sensor and repair the wiring. Prevent future water ingress by fitting a heatshrink sleeve to the CMP sensor wiring harness Fig1.1.
