Technical p1135 stilo fault code !!?!?!?!?
Any airbag fault should not come up with stop engine etc...
Fiat P1135 = Lambda sensor 1 pre-heater fault (high resistance)
I would like to think yes, but component replacement by fault code alone (which many garages do at cusotmer expense) is not the proper way to proceed.
The code has given a clue.
I would:
1) locate sensor and check sensor end wiring and connectors.
2) disconnect that connector and wiring and remove sensor checking for corrosion around the threads (this is often an earth return path)
3) check sensor with impedance meter. The fault code is suggesting the heater circuit has gone open circuit (or high resistance)
4) if all checks out OK then follow sensor wiring back into engine compartment and repeat step 3 at an appropriate connection point. This could be at another in-line connector or at the ECU socket.
You could just plump for replacing the sensor, which is hopefully the problem. Your call.

right have removed the sensors , upper close to exhaust ports and the lower sensor
stuck the fluke on the terminals , between the two white wires(3&4) resistance of 9.8 ohm on the upper and 9.7 on the lower sensor , the two other wires (no. 1 &2 ) are both open circuit .
any ideas ????
are they ok or both fubar ?
thanks again
it says turn off engine because if you keep driving and have an accident then your airbag will not deploy.
well im gonna say big thanks to s130 !!!
youve been great help thanks to you , tis cancelled the fault .
rechecked through the system with reader and a ok .
airbags still being gay , but its not my car , so dealer or garage it is me thinks .

I've got the same problem (P1135). In the code book it said that this problem was the fuel shut off solenoid and circuit malfunction. Is this the same as the above problem???
Only pleased to help.well im gonna say big thanks to s130 !!!

Did you do anything special or just connect and disconnet the sensor. If the latter then this would indicate dirty / oxidised / corroded connector contacts and making and breaking the connector would in many cases solve the problem. I would however have a really close look at the contacts and the rubber connector seal as the fault could occur again if the contacts are not properly clean and the seal intact.
Personally, although other disagree, I use WD40 to clean, lubricate and add a little extra moisture resitance. Alternatively you can buy switch / connector lubrication and cleaning spray.
Which code book?
As far as I know, P1135 is a manufacturer specific code.
Two examples:
On a Fiat P1135 = Lambda sensor 1 pre-heater fault (high resistance)
On a Nissan = Intake Valve Timing Control Circuit fault
With manufacturer specific codes one has to be VERY careful to ensure that you have the correct code description.
For a Peugot P1135 is:
3rd piston cutoff solenoid OR
Pedal position sensor circuit A Intermittent OR
EDC15C2 - 3rd piston deactivation. Short circuit to earth or open circuit OR
Intake manifold fault
....... take your pick
Having said this some manufactures do still try and use similar codes so a Saab has:
Front Oxygen Sensor, Preheating Current Low (and)
Heated oxygen sensor (HO2S) 1, bankd 1 - heater low input

got the code from a mates, mate who works in a garage. Would this fault effect the ABS, ASR and airbags etc? It doesn't come up as a fault when i'm driving only about 40-50% of the time. Other than that the car runs ok with no juddering or misfire
If P1135 is the only code then I'm not sure why or even if it would affect ABS,ASR & airbags.
You could have other gremlins going on.
