Dacia Logan 2012 Experiencing Engine Instability and Starting Issues: Could it be a Crankshaft Sensor Malfunction?

Hey! Sounds pretty similar to a problem I dealt with on my 2009 Dacia Duster. I had the same symptoms - unstable engine, drop in power, sporadic starting issues, and that pesky check engine light. Turns out it was a defective crankshaft sensor wiring harness/connector. Just like you, I suspected something wrong with the crankshaft sensor. Took the car to the garage and they confirmed it after running some diagnostics. They had to replace the wiring harness/connector for the crankshaft sensor. It wasn't exactly a walk in the park, but it wasn't anything cataclysmic either. In total, it was a bit time-consuming considering they had to remove parts to get to the sensor, clean up the area, and then install the new harness/connector. At the end of the day, it did resolve all those symptoms and got my trusty old Duster back in shape. Remember, every car problem looks giant but with the right hands working on it, it's often not too bad. Hope this helps! Cheers!

Hey there, Thanks for sharing, really helps to hear from someone who's been through the same scenario. Your experience with your Duster sounds a lot like what I'm dealing with my Logan! It seems then, that the crankshaft sensor wiring might indeed be the culprit here. And you're right, any problem seems daunting until it's tackled. Can't tell you how much I appreciate your reassurance! By the way, do you remember roughly how much the garage charged you for the whole fix, including the part and labor? And since the fix, have you noticed any other issues cropping up that are related? Thanks again! Cheers!

Hey there, Spot on! The issue I had with my Duster mirrors pretty much exactly what you're going through with your Logan. As for the cost, repairing the crankshaft sensor wiring harness/connector set me back around 170€. It included the part cost and the labor to get it fixed. I'm happy to report that ever since my mechanic sorted out this sensor problem, no other related issues have appeared. The old Duster is running like a clock now after the fix. Remember don't fret! A decent mechanic will guide you through it all and before you know it, your Logan will be in ship-shape, no more surprises! Cheers to you and your Logan!

Hey! Oh, that's a relief to hear! Your response gives me loads of confidence to handle this situation with the Logan. €170 doesn't seem too bad if it means getting rid of these dodgy symptoms which are driving me crazy. I can't wait to have my Logan back to her old self, running smoothly, without any surprises. Now, just need to find the right mechanic who can get it done. Cheers! Really appreciate you taking the time to share your experience. Helped a lot! Best to you and your Duster!
