My car just stopped starting. Got a code reader, the original codes that were being read were as follows

P0017 Cam/Crankshaft Position Corre;ation Sensor B-Bank 1
P0302 Misfire Cylinder 2
P0341 Camshaft Position Sensor A Bank 1 CKT Range/Preformance

I changed out the the crankshaft position sensor according to AutoZone, I have attached a photo of the part I bought it is the 70.99 part, I cannot locate where the "camshaft" sensor is the part that shows being 212.00.

After I changed the sensor I got a new code P0335 Crankshaft Position Sensor Circut Malfunction. Did that have that before. I got my husbands tester and tested it and there is no lights. See photos attached. The top part where the sensor plugs in has no power all across, I unplugged them all. I also tested inside the car and the ECM none of them light up? Anyone know what could be causing this issue? Any help is much appreciated. I attached photos. The car cranks, but will not fire up. Spark plugs were replaced not to long ago. I checked the FPR for leaks but did not see any. We are at a loss here on what could be causing the circuits to fail?

 

Have you checked your timing belt? If it breaks or is loose there could be more serious problems.

The camshaft position sensor is attached to this cover on the exhaust cam. You can barely see the 10mm bolt head facing down at the bottom right of the cover protrusion. You can also just remove the cover first but there are a ton of things in the way.

 

Thank you! I looked at that and thought no way that could be it. I will take a look at that.

 

Quick question from the photos above, I got a circuit malfunction code, and used my husbands tool to check to see if it would light up like it did when I checked all the fuses. On these connectors should it light up too when I put the tool in there like it does when you check the fuses?

 

I'm not sure if a continuity tester is the right tool for a cam sensor (hall effect switch).

 

Ok well here is the update, I have replaced both the cam and crankshaft sensors and the Fuel Pressure regulator, and it is still just cranking with no start. I am currently looking for the fuel pump relay fuse but I cannot find it, that was another suggestion I got. Do you know where it is located? I can hear the fuel pump working when I turn the key I can hear the hum, but I am still getting no start.

 

The only code I am getting now is P0341

 

did you check the wiring and connector into the cam position sensor?

 

I did, but I am not sure how to tell if something has gone bad with the wiring on it. Do you have any suggestions for anything else I should look at. Like the fuel pump relay, does this car model have one, do you know where it is located? 2001 S40 1.9T

 

fuel pump relay should be in the relay box near the firewall but that won't give you a cam shaft position fault code. That is typically the sensor, wiring or the VVT itself. The VVT is driven by oil pressure so if you are using an after market oil filter, change back to OEM and consider going to synthetic oil. Some people have been able to do a Seafoam treatment to clear the oil passages but its not uncommon to need to replace the VVT. For checking the wiring, see if the connector is cracked, any looseness in the wires, cracked insulation etc.

 

how about the end of this movie ?
living right the same situation !

 

Her problem may not be your problem though. Give us some details. Year, engine, any recent work, symptoms, etc.

 

Hi folks,
2001 v40 1.9L Turbo

I think I'm having a similar issue.

I recently replaced my water pump, timing belt, tensioner pulley and didn't do the proper process for the tensioner pulley. This resulted in my exhaust cam getting off a few teeth. This resulted in a camshaft code of P0341 and the engine wouldn't fire.
I ended up having to pull the cam cover off to reset the timing as I couldn't rotate the exhaust cam to the correct position. I put everything back together. Ensuring I followed the correct procedure to tighten the tensioner pulley. After getting everything back together the car started real rough, sometimes I'd be trying to start her for 20 minutes before she fired and I started getting P0335 and P0341. I figured I might have made another mistake but I checked the timing after multiple drives and I'm confident that it is correct (Marks are aligned on intake, cam, and crank).
However, I'm getting P0335 and P0341. I changed the cam sensor and crank sensors and was still having a heck of a time getting her to start. When I could get her to run she was very sluggish. I read somewhere else on these forums that this could be related to the fuel pressure regulator.
Last night I replaced the fuel pressure regulator, cleared the codes, disconnected the battery and let her sit for about 16 hours hoping that this would reset the computer and I'd be good to go. After reconnecting the battery today she fires up pretty well 3 out of 4 times (I started it up about 20 times and let it run for a bit). She feels responsive when she fires correctly, that fourth time though it's a real rough start, idle is low and inconsistent (deviates between 500 and 800 rpm) and she is very sluggish.
Still getting P0335 and P0341 with the occasional P0336.
At this point I'm thinking it's the computer or something in the electrical system.
My plan for tomorrow is to pull the camshaft position housing, verify that I have the piece on the exhaust cam seated correctly and start looking for a ground wire or something that might have been knocked lose. Other than that I'm at a loss.
As an aside I have a loud metallic rattling on that end of the engine, it's not coming from the pistons/valve and has been present for awhile. I'm thinking it's exhaust or turbo related, but I'm not sure if it could be related to the codes.
Any advice would be greatly appreciated.

 

I would check the compression and fuel pressure first.

 

I'll test those items and respond. Probably going to be a few days at least before I can get to it unfortunately.

 

Sorry for reopening an old thread and for my bad english 😁
I have exatly the same fault codes and I can not find any solution. Did someone manage to find out what was wrong?
