Renault Clio 1.2 16V 2001 - Code 634, running rough #

Posted by Dominic Casey on November 7, 2011, 5:49 pm

Year of Manufacture *: 2001
Engine Size and Code *: 1.2
( Optional ) ECU Type: Magneti Marelli
( Optional ) Scanner Used: Snapon Solus

Hi all

I have the above vehicle in the workshop running very rough and not taking the throttle. The glow plug light is staying on even though its a petrol. I pulled a fault code 634 "Inlet Air Circut Current"

Can anyone tell me what this means ?

Thanks in advance
Dominic

Hello Dominic, I would assume it refers to intake air temperature sensor. This might be of use http://www.acbautoelectrics.co.uk/

Hi Dominic,

For what its worth, the IAT sensor appears to be between the inlet manifold on nos 3 and 4 cylinders. However, I cannot see that causing any running fault.

The fault code is unknown to me. Is it possible to get an EOBD fault code out of the vehicle? The running fault sounds like a problem with the MAP sensor, but with very little info to go on, its difficult to say. I think we need more info in the way of emissions and live data, especially on the MAP sensor.

Regards

Pete M

Hi Dominic,

"Inlet air circuit" is a common DTC on Reaults, it is unlikely to be anything to do with Inlet Air Temp sensor! More likely to do with inlet air leak or poor manifold vacuum.

It sounds to me like you may have a throttle body problem with this one. Check manifold Vac and remove manifold and TB thoroughly clean and refit then "reset autoadptives"

If this does not work it may need a new throttle body. The last time I priced one they were ~£350.00 from Renault and no one else at that time supplied them aftermarket.

Also check wiring where security plate rubs on ECU harness close to multiplug. And confirm MAP sensor is reading correctly.

HTH
