(T) Check Engine

Personally I'd favour the £19.99 one as it is stand alone.

I'm sure others will favour the PC based version.

Thanks for your reply.

Is there a great deal of difference of what you can do between the two? Im guessing the PC based one will have a lot more options? Ive got a laptop I can install it on.

Just read another thread on here reporting a similar problem and Fiat said he needed a new turbo. Im guessing if the turbo was faulty it would stop working completly? Im out of warranty by a year and if it is the turbo it sounds like a bloody expensive job!

Would anyone be able to point me in the right direction of where to look to check for any splits. Would it be under the bonnet or actually underneath the vehicle.

Sorry if its a silly question!

Follow the induction pipework all the way from the grill to the Throttle body, under the bonnet. Check all pipes for splits and check all pipe connections are tight.

I have a different explanation for that code:

P0236 Turbocharger Boost Sensor A Circuit Range/Performance

From that it would look to be the MAP sensor (Mass Air Pressure) which tells the ECU how much boost is being given by the turbo.

Either way, I would take it to a good independant garage, they will sort it out for you. If you supply them with the code, at least they have a starting point.

Thanks Adam.

Although just curious how you got a different explanation to that code compared to the explanation kwik fit got. Does it depend on the machine used to connect upto the car computer.

Just took the car out for the first time today and it had no turbo. Pulled over after a few minutes, turned off and then back on and had full power!

Had a look under the bonnet and saw a variety of pipes. I dont suppose anyone could point me in the direction of the turbo so I can work back from there checking the pipes. Is it around the actual engine?

The codes are quite open to some debate in their meanings, Kwik fit may have a different definition to the one I have.

The pipe is unlikely to be split, as you would hear a massive rush of air, like a loud hiss every time the turbo spooled up. This is because some of the boost pressure would be lost through the hole, a problem that is not likely rectified by a simple switch on and off again.

FYI, the turbo is at the front of the engine, in the picture below:



Edit: To add to that, the MAP sensor is in the intake manifold (no 6 on the diagram)

Thanks for your reply.

Im guessing its the part labeled SGR 10252 in the picture?

I had a feeling it might not be the pipe, as if it had a leak im guessing the problem would be permenant, rather then intermittent.

At the moment theres no additional noises or anything else when started.

I know the best option would be to take it straight to Fiat, but finances at the moment are a little bit strecthed! Im also a bit dubious about local garages - You see so many reports where they say the problem is something more expensive then what it is. I wanted to try a few things before taking it to a garage.


Iver ordered the PC kit to hook the car upto my laptop (which is also away for repair!) and hopefully see what that comes back with.

You metion the MAP sensor in a previous post, is that something which would just need replacing, or would a clean (I know a few people say clean sensors first) be an option?

Correct, turbo is SGR10252

PC kit will probably just give you the same trouble code again, but might be wise to double check it anyway. Does the "Check Engine" stay on after you restart the engine?

MAP sensor is a replacement only job I think, but this is stabbing in the dark. The Fiat part number for this sensor is 55206797, but is quite pricey so I wouldnt go around changing it without being certain that is the cause. Maybe you could disconnect the wiring from the sensor, and see if the fault is constant? Im not sure how accessable the wiring is though.

The light stays on constantly whether the turbo is working or not.

I'll have to have a little look around on the net about the location of the MAP sensor and give that a try. If it does turn out to be that, ive found one on ebay for £49. Different part number, but labelled for the 1.3 Grande.

The part number thats listed on the eBay site is the General Motors number, its identical to the Fiat part with the number I listed above

Ah! Thanks.

One last question, I dont suppose anyone knows of a guide that shows the locactions of all the parts? Similar to a haynes manual online?

Took it down to a local garage on Friday as still waiting for my laptop to come back from repair.

They hooked it up and it had the same error and also one regarding the map sensor.He turned them off, took it for a test drive and they didnt come back on and the car ran fine.

He thinks it might be the valve sticking which I was quoted £130. (£99 part and £30 labour).

Drove the car away and it came back on, so got it booked in tomorrow for them to replace the part. Fingers crossed that does the trick!

One more question, does anyone know where I can get a replacement mirror? Some vandal must have booted it off. The casing it ok, just the actual wingmirror is cracked.

Also! Is it a single or twin cam on the 1.3 mjet 90bhp?

The glass is available here http://shop4parts.co.uk/?name=store&...roducts=Search

I guess yours will be the heated ones

Thanks adam, much appreciated.

Wow, thats great and a lot cheaper then I thought! Luckily there not the heated ones!

Any idea about the cambelt on this GP?
