Renault megane scenic 1.4 been on diagnostic machine and came up with this code, relates to manifold air pressure sensor, we think, absolute pressure sensor, any help if anyone nos would be grateful as weve been told it will cost 120 plus vat already spent 100 on it today

Re: 202 cat error
Where the rubber pipe joins manifold on engine their is a plastic fitting that the pipe fits onto ,if you look carefully you will see where the jubille clip and flantened it a bit ,thats your reading no doubt .if it runs ok ignore the fault codes,as a matter of fact iam surprissed you have evan managed to read it as its all encrypted software and it will show different codes to what it will show on a renault machine

It could be anything, maybe a sensor, fuel problem, electrical fault, throttle body, etc You should have a garage run a diagnostic to get more info then...
Better to ask your question with more detail on a Renault forum, you will have to give as much info as possible. Renault Forums Independent Renault forum Powered by vBulletin
sounds like the MAP sensor but i'd have the OBD codes read, as this will pinpoint the sensor/switch and will save you time and money as there are a few things that could cause this , and searching blind and changing parts that may not need changing
Fault Code Definition The Manifold Absolute Pressure Sensor/Barometric Pressure Sensor measures the rise and fall of the air pressure inside the Intake Manifold. This provides critical data needed for the Power Train Control Module (PCM)
to control the Air Fuel Ratio, the Ignition Spark Timing, and many
components of the Emissions Control Systems. The Manifold Absolute
Pressure/Barometric Pressure Sensor converts the Intake Manifold air
pressure into a voltage that is high when the Intake Manifold air
pressure is high and low when the Intake Manifold air pressure drops to a
vacuum. The P0108 code indicates a high voltage input from the Manifold
Absolute Pressure Sensor/Barometric Pressure Sensor to the Power Train Control Module. Symptoms
From what you have described in your post and speaking from personal experience and without using a diagnostic tool there is a high possibility there is a problem with your camshaft sensor,
Part number 8200285798 for this is a common problem on these models.
DF119 or code DTC 0340 is the code given for this fault by Renault's diagnostic tool in some cases the code does not store itself into memory making diagnosis of the problem more difficult.
It would be interesting when you solve your problem to let us know.
Hope this information was helpful!
Most likely to be a faulty resistor block, which has 3 resistors and a thermal fuse controlling fan speeds 1,2 and 3, maximum speed 4 by-passes the resister block. It may also be poor electrical connections to the resistor block caused by overheating. Renault ask for approximately £350 to carry out repairs, a replacement resistor block will cost £50. If you decide to carry out the repairs yourself, be advised that if you are not competent to carry out such work you, could cause electrical damage or worse an electrical fire.
