p0108 error code in suzuki car

today will learn abot what is error code p0108 in suzuki car  

what happan when comes p0108 code in suzuki car 

whats means of this code in suzuki car 

 how we resolve to this mater of this code in suzuki car 

  • P0108 is caused when there’s too much voltage coming from the MAP sensor to the ECM.

  • P0108 Most commonly caused by a bad MAP sensor.  Vacuum or wiring issue are the next most common causes.

  • Usually results in a rough running vehicle. p0108

  • A voltage meter is required to diagnose the MAP sensor. In case of code p0108

 

 

The first thing that you should do is test the MAP sensor itself.  A good voltmeter is necessary for this step

                                                         

P0108 is a generic OBD-II trouble code.  It indicates your Suzuki car MAP (manifold absolute pressure) sensor’s voltage reading is outside of the normal operating range.  The voltage is too high.  It’s most commonly caused by a bad MAP sensor, wiring issue, or vacuum leak.

The MAP sensor measures the air pressure coming into your vehicle engine and sends that signal to the ECM.  It does this by sending a voltage ranging from 1 to 5 volts.  1 volt would be idle speed.  The signal should be at 5 volts whenever the vehicle is at wide open throttle.  P0108  is triggered whenever the signal from this wire is MORE THAN 5 volts, which shouldn’t happen.

can see in this pic         

P0108 can also trigger if the ECM thinks the voltage coming from the MAP sensor is higher than it should be at any given time.

  • Poor Gas Mileage

  • Rough Running/Stalling Engine

  • Motor Won’t Start at All

  •  * Dark path smoke

  • Check Engine Light

.  It does this by sending a voltage ranging from 1 to 5 volts.  1 volt would be idle speed.  The signal should be at 5 volts whenever the vehicle is at wide open throttle

P0108  is triggered whenever the signal from this wire is MORE THAN 5 volts, which shouldn’t happen.

The 3 common reason in this case

1.       Faulty map sensor  

2.          Vacuum Leak

3.         Wiring Issues

.MAP Sensor

First thing to do change map sensor at first and ofter then check all these things 

.Vacuum Leak

A vacuum leak is a very common reason that P0108 is triggered.  If there isn’t enough vacuum going to the MAP sensor it’ll give a higher voltage reading than the operating conditions suggest should be there.

The vacuum supply to the MAP sensor could have a leak, or there could be a vacuum leak around the engine as a whole.  Check all the vacuum lines on the engine.  Check to see if any of them appear to be brittle, melted or cracked.  If they are, replace them and see if that solves the problem.

.Wiring Issues

The easiest thing that you can do when P0108 is triggered is check your Swift’s wiring harness.  Is it plugged in to the MAP Sensor tightly?  Does it have any visible signs of damage?  Follow it as far as you can and make sure.  It’s going to have a ground wire.  Make sure that ground is plugged in tightly.
