Code No. P0606: Engine-ECU <M/T> or Engine-A/T-ECU <A/T> Main Processor Malfunction

FUNCTION

• The engine-ECU <M/T> or engine-A/T-ECU <A/T> check whether the microcomputer, which performs the drive control of the throttle valve, is normal.
  

TROUBLE JUDGMENT

• Ignition switch is ON position.
  

• Malfunction of the microcomputer.
  

• Ignition switch is in ON position.
  
• Battery voltage is 6.3 V or more.
  

• Throttle position sensor output voltage is 4.1 V or less.
  

• Malfunction of the main microcomputer basic voltage.
  

• Ignition switch is ON position.
  
• Throttle position sensor (main) output voltage is between 0.4 and 4.8 V.
  

• Malfunction of the throttle position sensor (main) input interface.
  

PROBABLE CAUSE

• Failed the engine-ECU <M/T>
  
• Failed the engine-A/T-ECU <A/T>
  

	Replace engine-ECU <M/T> or engine-A/T-ECU <A/T>.
