title: How to get OBD2 Fuel Level reading from Wagon R 2010 model
body: <p>I want to measure current  fuel level inside my car's fuel tank using OBD2 bluetooth/USB adapter.</p>
  
  <p>When i try to query that PID i got following data as "NO DATA" while at the same time i can check other PIDS like RPM and all data comes fine.</p>
  
  <p>I have small python program which reads its but i am unable to get it.</p>
  
  <pre><code>import serial
  
  #ser = serial.Serial('COM12',38400,timeout=1)
  #ser.write("01 2F \r")
  #speed_hex = ser.readline().split(' ')
  #print speed_hex
  #convert hex to decprint ("SpeedHex",speed_hex)
  #speed = float(int('0x'+speed_hex[3],0))
  #print ('Speed',speed,'Km/h')
  ser1 = serial.Serial("COM12",38400,timeout=1)
  #ser1.write("ATZ \r")
  #ser1.write("ATE0 \r")
  #ser1.write("ATL0 \r")
  #ser1.write("ATH1 \r")
  #ser1.write("ATSP 5 \r")
  ser1.write("01 0C \r")
  fuel_hex= ser1.readline()
  print fuel_hex
  #convert to hex to decprint ("FuelHex",fuel_hex)
  #fuel = float(int('0x'+fuel_hex[3],0))
  #print ("Fuel in Per",fuel)
  </code></pre>
