Problem with Peugeot 206

Hello Friends of the Forum, I need if someone can help me with a problem that I have with a Peugeot 206 XR 1.6 year 2005.
I appear the following error codes
P1336
P1339
P1340
Check the distribution, take advantage of changing the belt
Check the cigaeñal pocition sensor and clean it but nothing
the Pirde Pirte power and that walking in two or three cylinders. Please if someone can help me from hand thank you very much

Hello; Indeed, these codes refer to the crankshaft position sensor. Of course, it is not enough to clean it, if you are bad, you must change it.

SIP but it will be the sensor is so weird that in a car, with 100,000 km a sensor is found, or it will be a factory problem

Boris, it is not something very normal that the CKP fails but you have to keep in mind that in any car more than 100,000 km is the possibility that anything begins to fail you, I would advise you to change it since if you continue like this at some point your car nisído will turn on. Greetings and I hope it has been your help (Eye discards any factory problem since it can perfectly have failed before)

You were right, M no longer part. Tomorrow comes a friend who has one of them. We are going to change the sensor to see what happens, from there comment thanks for your answers
