OSCILLOSCOPE 029 P0101 and P0113 MAF fault -Location of the mass flow meter connection pins on the vehicle. The electrical diagram and the measurement of the electrical magnitudes with the PICO oscilloscope are used, supply voltage, analogue ground voltage, air temperature sensor output voltage, voltage and frequency of the air flow meter verification and control signal, voltage and frequency of the air flow meter measurement signal. These measurements are made with the component working correctly. A detailed explanation is made of how the oscilloscope channels must be connected to the electrical installation of the component on the vehicle and how the measurement channels must be adjusted to have a good visualization of the electrical magnitude being measured. -Location of the cause of the P0113 defect (interruption of the output line from the air temperature sensor to the computer). Description of the defect code, simple explanation of the possible electrical causes of this defect. Reading and analysis of the parameters read with the ICON diagnostic tool via OBD. Checking the electrical parameters analog ground and temperature sensor output voltage with the PICO oscilloscope, analyzing the measured values. Procedure for locating the interruption in the air temperature sensor signal output circuit. Locating the cause of defects P0101 and P0113 (interruption in the analog ground line). Description of the fault codes, simple explanation of the possible electrical causes of these defects. Reading and analysis of the parameters read with the diagnostic tool via OBD. Checking the electrical parameters flow meter supply voltage analog ground, temperature sensor output voltage, voltage and frequency measurement of the output signals in the frequency of the meter and control signal with the oscilloscope. Analysis of the measured values, locating the interruption in the analog ground line. We performed the tests with a PICO PQ178 oscilloscope, the product link is this https://www.miac.es/tienda-producto-v... With the diagnostic equipment we verified the fault codes and analyzed the parameters with the Autocom ICON, https://www.miac.es/tienda-producto-v...
