P006A-00 manifold absolute pressure sensor

Fault code P006A-00 manifold absolute pressure sensor-mass of volume air flow correlation is related to the problem with faulty manifold absolute pleasure sensor, faulty air mass sensor, leak pipe or leak intake manifold. This fault code could be store in engine control module. When engine control module recieve wrong signal from manifold absolute pressure sensor or air mass sensor. In some cases this fault code store in engine control module while driving at high speed or at high engine revolution. While sometime it happens driving at low speed also. When fault code store in engine control module while driving at high speed. It means there is some leak at air intake area due to which engine control module set fault code P006A-00 manifold absolute pressure sensor and a warning message ” Performance restrictions” On cluster meter.

This is the common problem of air intake leak in land rover all models vehicle like sports, evoque, Vogue. This problem can be solve by replacing leak intake manifold or buy repairing intake manifold.

Causes of P006A-00 manifold absolute pressure sensor :

  • Faulty manifold absolute pressure sensor.
  • Faulty air mass sensor.
  • Leak intercooler.
  • Leak intercooler pipe.
  • Broken or leak intake manifold.

How to trouble shoot :

There might be two things in this situation. One is there is some electrical problem like faulty manifold absolute pressure sensor, damage wiring harness, faulty engine control module. The other thing that can be happen is leak at air intake area like leak at intercooler pipe, leak at intake pipe, leak at vacuum pipe, leak at intake manifold or the other thing is failure of turbocharger.

  • When found warning message “performance restriction” At instrument cluster. It means that there is some issue with engine performance. To find out what is wrong with engine performance you need to scan vehicle with the help of scan tool to find out the fault code or the reason behind this warning light on cluster meter.
  • When found fault code P006A-00 manifold absolute pressure sensor store in engine control module. This fault code is indicating problem towards intake manifold pressure sensor. So first check reading of manifold absolute pressure sensor also air mass sensor. If vehicle is V6 or V8 engine than there will be two air mass sensor and one manifold absolute pressure sensor.
  • Sensors reading should start increasing as accelerator pedal press and match the desire reading according to manufacturers. If readings are increasing as accelerator pedal press than it means that sensor are working fine. But if readings of sensor’s are not increasing as accelerator pedal press than it means that sensor are not working fine and need to be replace.
  • If any one or two sensor reading is not increasing than check sensor wiring harness if found any damage wiring harness or any loose connection at sensor than repair that. If still reading not increasing as accelerator pedal press than replace that sensor after which that sensor reading should increasing. which have been changed and it should meet the desire pressure according to manufacturer.

Case #2

  • Now if sensor’s start showing reading and its value increases as accelerator paddle press. Than it means that sensor’s are now working fine. After replacement of faulty sensor take a test drive of vehicle at speed of above 90-100 km/h. If still there is “power restriction”warning on cluster meter or fault code store in engine control module. Than it means that there is some leak at intake manifold or at somewhere of air intake which is now confirm. From where engine take extra air into combustion engine due to which this fault code store in engine control module.
  • Start checking leak from all those four silicon pipe which is use to connect intake with each other. Most of the time from these four silicon pipe connector have leak due to improper fitting. If found leak there than remove that pipe and try to fit that pipe properly.
  • When it is confirm that there is a leak in intake manifold perform high pressure smoke pressure test to find leak. You will see a lot of video at YouTube to perform smoke test you can see that from there.
  • Perform high pressure smoke test to find leak at air intake area like, intercooler, intercooler pipe, vacuum pipe or intake manifold. Most probably you will find leak at intake manifold area as it is a common problem in land Rover vehicle.
  • To make it easy make two different partition, disconnect intake from throttle body. Remove manifold absolute pressure sensor. At the whole of sensor insert smoke pipe and close that properly. So that the smoke and pressure should not leak from there.
  • If leak is at intake manifold than you should carefully perform high pressure smoke test as intake manifold will have very minor leak which cannot be seen easily. Fill smoke into intake manifold at high pressure. With the help of blue torch try to find leak from where you will see that smoke is coming out.
  • When find leak replace that leak part so that engine can not take any extra amount of air into combustion engine. Due to which there is a problem of power restrictions.

Solution of P006A-00 manifold absolute pressure sensor :

  • Replace faulty manifold absolute pressure sensor.
  • Repair damage wiring harness.
  • Replace faulty engine control module.
  • Replace leak intake manifold.
  • Repair or replace any other leak part.
