OBD malfunction indicator light status on stored diagnostic trouble codes po325, po335, p1336 . Car will not pass OBD test.

You will need to get a Good Mechanic to look at this. There are 3 completely different problems here so it will need to be properly checked out. I've listed the Trouble Code definitions below.
-The knock sensor looks for signs of the fuel igniting at the wrong point in the sequence.
-The Crankshaft position sensor checks the pistons are in the correct position for the engine electronics to be in the correct sequence.
-The Air Control system is a set of valves that adjust air flow through the engine when running at different speeds. (Slow needs less air, fast needs more air).
Knock Sensors and Crankshaft Position Sensors can be in some ridiculous places on an engine and usually need major surgery to get to them. Air control systems could be anything from a 'sticky' valve to a faulty sensor.

P0325 = Knock sensor (KS) 1, bank 1 - circuit malfunction
P0335 = Crankshaft position (CKP) sensor - circuit malfunction
P0505 = Idle Air Control System

Renault Scenic P242F Engine Trouble Code When the check engine light comes Renault Scenic P242F code on the first you should check is the gas cap. Pull over, retighten it, and take a look at the cap to see if it has any cracks in it. Continue driving and see if the check engine light turns off. Alternately, you can purchase a gas cap for about $3 at an auto parts store. All you need to do is take the old one off and screw on the new one. If you've already made it to the store, you might as well just replace it. While not car-threatening, it's good to take care of this right away to improve gas mileage.

Renault Scenic P242F Code Meaning :

P OBD-II Diagnostic Powertrain (P) Trouble Code For Engine Fuel And Air Metering (Injector Circuit Malfunctions Only) O2 Sensor Heater Circuit Malfunction Turbocharger Boost Sensor A Circuit Low When you check Renault Scenic car engine light came on code P242F the reason should be . However manufacturer may have a different definition for the P242F OBD-II Diagnostic Powertrain (P) Trouble Code. So you should chech it on our car models. P242F Fault Symptoms :

1. Check engine light comes on
2. Engine stalling or misfiring
3. Engine performance issues
4. Car not starting

If one of these reasons for P242F code is occuring now you should check P242F repair processes.
Now don't ask yourself; What should you do with P242F code ?
The solution is here : Renault Scenic P242F Possible Solution : Disconnected, dirty or fouled spark plugs are common causes for engines that won't start. Spark plugs typically need to be replaced every season or 25 hours of use. You should also check that the spark plug gap is set properly. If your spark plugs look good, problems with your ignition system can also preventing a spark. These can range from a faulty spark plug lead, shorted kill switch or flywheel key damage.
P242F OBD-II Diagnostic Powertrain (P) Trouble Code Description P242F OBD-II Trouble Code The Powertrain Control Module ( P242F code. Reason For P242F Code The reason of P242F OBD-II Engine Trouble Code is O2 Sensor Heater Circuit Malfunction. Parts or components should not be replaced with reference to only a P242F DTC. The vehicle service manual should be consulted for more information on possible causes of the fault, along with required testing.

First step is to have the code or codes read.If the "check engine light" is on there will be a reason and should be a code or codes to be read.Once you have the codes,you can determine the correction needed to get that "check engine light" out and a valid emissions test completed.Get back to us with the codes found.

Diagnostic Test Code (DTC) P0700 is an informational code that is stored in the Engine Control Module (ECM) That informs the diagnostic technician that there are codes present in the Transmission Control Module (TCM) and that the TCM has requested the Malfunction Indicator Lamp (MIL) (AKA - Check Engine Light) to be turned on. This is because the MIL is controlled by the ECM and cannot be turned on directly by the TCM. So, the TCM requests the ECM to turn the light on. To find out the nature of the failure that caused the P0700, one must scan the TCM to retrieve the fault codes stored there. Please note that MOST generic OBD code readers cannot access the TCM - this is the reason for the P0700 code to set in the ECM (to alert somebody with a generic code reader that further diagnosis is needed for the TCM).

You should have the vehicle's OBD-II trouble codes read. Although the light goes out, there is an intermittent problem and likely there will be codes still in the memory.

Auto parts stores sometimes read the codes for free, or you could buy a code reader. You can also find a trouble code diagnostic listing at http://www.obd-codes.com

First the fault codes,
U110C is No Fuel Level Bus Message
U0155 is No Cluster Bus Message.
Unfortunatly you have to be able to communicate with the instrument cluster with your scanner to diagnoise and I do not think an aftermarket scanner can do this.

P0335 and P0336 Engine crank sensor malfunction
To test this code, have a visual inspection of the location and wirings of the crank sensor. If the engine has a cam sensor, you might mistook it as the crank sensor (it is a good idea to contact ATS that can research this for you). Check the sensor wires for insulation making sure it is getting a voltage signal as shown in the wiring diagram. Sometimes, the wires itself is soaked with dirty oil causing the sensor to fail. If OK, check the engine timing belt system for any slack which can also cause the sensor to throw in the code. If all of these prove OK, remove the crank sensor and check it for resistance as compared to the standard specs. Lots of times, if the sensor probe end is contaminated with oil or cracked, this can only be revealed after the crank sensor is removed
