Common Symptoms For Mitsubishi Celeste B3737

  1. If the transmission functions normally and the code doesn't return, then it was likely caused by transmission slippage due to a low fluid level/pressure condition. If the code returns and the transmission slips or suffers from delayed engagement, check pump pressure using a manual pressure gauge
  2. A suitable OBD-II scanner (or code reader) and a digital volt/ohmmeter will be most helpful in performing a successful diagnosis
  3. If the initial resistance is within specifications, leave the leads of the digital volt/ohmmeter connected and heat the resistor with a heat gun
  4. Check local, state, and federal laws before removing emission related components.

Mitsubishi Celeste B3737 Troubleshooting

A sure sign of this is smoke or steam being emitted from underneath the hood. The ignition timing could be set incorrectly and will require adjustment. If, when looking under the hood, you notice that the drive belts appear loose, they need to be tightened or completely replaced. If there is a noticeable pool of fluid underneath the car, this could be a sign of the cylinder head gasket failing. That will be confirmed in the form of billowing smoke being blown from the exhaust system. Parts or components should not be replaced with reference to only a Mitsubishi Celeste B3737 DTC. The vehicle service manual should be consulted for more information on possible causes of the fault, along with required testing.
