How to clean the MAP sensor of the Nissan Qashqai

Model: Nissan Qashqai J11 - Years 2014-2022
Part: Crankshaft position sensor

In this video we see how to clean the MAP sensor of a Nissan Qashqai: starting by removing the cover of the monoblock, and underneath we immediately find the absolute pressure sensor, next to the throttle body. It detects the pressure of the intake duct, and then the ECU manages the right amount of diesel to send to the injectors. Obviously, if the sensor is dirty, the detection will be wrong, and consequently also the information it sends to the ECU. It is a cleaning that is convenient to do together with the EGR cleaning, because it is right nearby. But now we will only focus on the sensor. We remove the electrical connector, then unscrew the fixing screw and remove it. We must clean it with a specific product, which leaves no residue, like WD-40 for contacts. We find it for 9.99 euros on Amazon with the code B00GTV24JE, free delivery for Prime customers. We let it dry well, grease the sides with a drop of oil and put it back in place: we put the bolt back on and then reattach the connector. Job done.

How to Check the Oil Level on a Jeep Renegade?

This should be pulled out and thoroughly cleaned with a cloth: once cleaned, reinsert it back into its tube and pull it out immediately after. This way, you can check that the oil mark is between the minimum and maximum levels; finally, you can place the dipstick back in its tube.
