Fault code :o(

Kentishnomad · Sep 5, 2015

Hi guys, my engine management light has been coming on and off for a while now, and now it just stays on. The forklift fitter at work brought his diagnostic doobrey in and plugged it into the car and a fault code P0237 is showing. I googled it and it says turbocharger low pressure A circuit (or something along those lines). I have not got a clue what this means and I have no mechanical knowledge, could someone enlighten me as to what this might mean?

Either the turbo charger is giving low pressure or the sensor has failed i would think.

Hi Kentishnomad.
depending what year your FL is the turbocharge sensor can be one or combined, it is also know as the MAP sensor, or in case of 2003 onwards FL will also have a sensor in the hose of the intercooler, both can be cleaned with a little carb cleaner, also I would clean out the manifold and EGR, check the wiring going to both the sensors if you have both.

Map senor is found on the left of the manifold as you are standing in front or the FL, some say the right hand side/end of the manifold.

The Turbocharger boost temperature sensor is found at the front on 2003 onwards in if the intercooler hose check the wiring is in tact a fitted ok.

I change and clean EGR, manifold, Map and TbTs each year as part of my service, pics below
