I really need to know where the position of the Camshaft Position Sensor is on my Diesel 1.9 8v Bravo, I have a fault code on the OBD reader as p0335 this happened when I trouble with my ERG Valve recently which I have re-placed now as I have mentioned in another thread (Hopefully resolved, no related code yet) I did read on the net somewhere that Camshaft Position Sensors can become faulty, get to a high temperature then suddenly stop working and cut the engine out! This is what is most likely what is going here! Help please! Where the hell is that sensor? It's driving me bananas!


I did notice this older thread, is this at all similar? What you think guys? https://www.fiatforum.com/punto-mk2...jtd-crank-rpm-sensor-removal-replacement.html

See this:

Thanks for that! Was looking in there yesterday, late in the day and all and I have ordered that part: FEBI 28386 Camshaft Position Sensor which says compatible on many sites should be the end of my ignition stalling, hopefully Fingers X


The other thing that confused me was the other Camshaft Position Sensor presumably for the 150 bhp version: FEBI 28130 Camshaft Position Sensor sometimes comes up as sometimes compatible for the 120 bhp which is confusing! I'm 90% certain I have ordered the right one! Looking at the picture!

This has me a bit stressed I can tell you! I have got the top timing belt cover off! I can see the sensor! I see a nut on the right of the sensor bracket which is assessable, I undone this nut, but to no prevail of removing sensor bracket or sensor there seems to be another fixing to this sensor to the left an Alan type under the wheel which the timing belt runs, I'm afraid to proceed any further! I'd thought you would be able to undo the retaining nut and slide the sensor out while disconnecting the connector the other end? Finding this very frustrating at the moment! Not as easy as I thought!

The right nut I can undo! The other fixing on the bracket hidden under belt(?) appears to be possibly a 4mm Alan or possibly just a hole instead it's hard to see, suspiciously think Fiat have made this hard to get to and possibly very hard to un-do! I don't want to take the belt off to access it! There must be a solution? Apart from going to the Garage!

Unfortunately you need to remove the pulley in your photo, and to do that, the timing belt. I think it's time for a trip to a garage, and replace the timing belt and water pump at the same time.

Engines aren't as simple as they were in my Mk1 Cortina. I stripped that completely, down to the last nut and washer, and rebuilt it after a rebore, all without the benefit of a Haynes manual. Now I wouldn't even think of doing it.

I did actually think this might be possible without taking the pulley completely off! Just undoing the pulley nut and moving it back approx. cm to give me the clearance I need? Obviously this would be a last ditch attempt to get the sensor arm off and would need to mark every where on the belt and pulleys just in case! It would be slightly easier if I could slack the tension slightly on the cam belt tensioner it's self to do this? This is just a theory though! Is this possible with great care? Really need to see properly what that other fixing is? A pin? Or is it threaded like the nut side? If it's a pin it might work like a pivot point, so the sensor can be replaced? There is not much on this on the net I have looked, apart from the eLearn guide!
But yes I do agree if I did get the garage to do the job the belt and water pump might as well be changed and the timing checked!


Here's a picture of the new sensor!

Don't even think about doing that.

Or that.

You have to lock the cam/crankshaft, then adjust tension, then tight the bolt on the pulley.

Thanks! Looking at Garage quotes now! Pain in the bum this sensor, other engines it's simply replace the sensor, plug and go! Think the other version of the engine is? The 150 bhp model. Probably getting the belt done now 20K too early!

Re: Where is the location of the Camshaft/Crankshaft Position Sensor?

Hi, Guy's Just want to let you know that the car is now sorted! I got the camshaft belt replaced + tensioner and water pump the camshaft sensor was replaced too underneath camshaft pulley! But although the belt needed doing in about 15K anyway the Camshaft sensor was not the main problem with the car cutting out it was the Crankshaft sensor instead, which I had confirmed by a RAC man. One of my suspicions was correct, it was the Crankshaft sensor that was faulty when the engine got hot and dying on me, think it works on a magnetic pulse and has a reed switch inside that can become sticky and intermittent when worn out!


I replaced the Crankshaft sensor myself (not the Camshaft sensor) which is located in the middle at the bottom at the back of the Fiat Bravo 1.9 8v diesel engine, it is completely impossible to see or replace this sensor looking down from the top of a complete engine and you will need to take the bottom guard underneath your car (Bravo) to access, you will need plenty of head and arm clearance to get to the Crankshaft sensor i.e. Ramps, Jack or pit! I jacked my car up and wedge ramps on there side as a safety precaution, but just managed to undo it with a Alan key. Now I'm happy!


Do not get confused between the Camshaft sensor and the Crankshaft sensor like I did! The camshaft it is at the top of the engine to the left under the Camshaft Pulley the Crankshaft sensor, middle bottom, which I just explained! The fault code I got previously on my OBD reader was P0335 which is Camshaft position sensor,why I went for the Camshaft sensor instead, it was all along the Crankshaft sensor! Also, if you do come up with this code: P0335 it could possibly be the Camshaft sensor especially if the car does have too much trouble starting, but if the engine is cutting out or juddering with this code when the engine is warmed up it's more likely the Crankshaft sensor instead! Hope this helps someone later?

Camshaft sensor! Everyone got that?!
