Engine light on and traction control light on engine up and down and cutting out.Been told its the mass air flow meter
SOURCE: Cleaning the Mass Air Flow Sensor
i will try to help. 171/174 indicates lean condition in engine. the mass air flow sensor is located in the rubber tube going to throttlebody. you can try to clean it. using mild carb cleaner safe for sensors, remove sensor from tube. spray clean the tiny wires located in the cylinder. do not touch them, they are very delicate. these engines are also notorious for leaking intake gaskets and faulty pcv valves. these will all set these 2 codes. feel free with anymore questions.
SOURCE: Where is the mass air flow sensor located on a jaguar x-type
hi from the uk the location of mass air flow sensor on x type jag is as follows==it is on the r/h/side of the air filter cover with jaguar embossed on top? this sensor is just prior to the intake hose that connects to the motorised throttle body from filter connections underneath it to unplug and meter is held by two screws ?if memory serves ? may i suggest you remove the large hose and use a little wd40 or similar to clean /lubricate the throttle butterfly in throttle body throat at this point so as to prevent future sticking upsetting of idling ? hope this helps ?

hey rob_andersen,
yes their is a way to replace the mass air flow. Get a can of brake clean or throttle cleaner, throttle cleaner is going to work best. remove the until and spray it down with throttle clean, let it dry for about 15 min. and reinstall it.
Now a little warning for you, IF their is no visual damage to the mass air flow then you can do this successfully. Now the reason why I always replace them instead of spraying them down is because is MOST cases the mass air flow will start acting up again. Sometimes it takes a weeks, sometimes months, sometimes years its hard to say.
But the worst you have to loose, is it doenst work an your out 5 bucks for the can of fluid.
