OBD Code P045C - Exhaust Gas Recirculation "B" Control Circuit Low

<<See All OBD Codes

OBD Error Code P045C? EGR? Circuit Low? Baffled, too many terms to comprehend? Calm down. With Parts Avatar everything is easy. Here’s all you need to know about the Error Code. The Error Code P045C, a generic powertrain code, is a diagnostic trouble code (DTC) applying to all the vehicles with an Exhaust Gas Recirculation System. Widely ranging in brands from Land Rover, GMC, Chevrolet, Dodge, Chrysler, Ford, Toyota, Honda, etc (specifically not just limited to these). Although basic, the process of repairing may vary from model/make. These engine codes also direct to a failure in the EGR (exhaust gas recirculation) system, specifically the electrical aspects. Also, it should be noted that the EGR is an integral part of the vehicles emission system, that functions to prevent the formation of harmful NOx (oxides of nitrogen) in the cylinders. Therefore, the code should be handled attentively.

Elaborating further, the EGR operates with the help of an engine management computer. The computer opens and closes the EGR and also instructs the load, speed and temperature in order to maintain the proper cylinder head temperature. The computer activates the two wires present on the EGR that connect to the electrical solenoid. The potentiometer located in the EGR Solenoid signals the position of the EGRs pintle (an operating mechanism opening and closing the passage).

 

What causes this problem with the Random/Multiple Cylinder Misfire?

 

  • Battery voltage short to.
  • A defective Connector with pins pushed out.
  • A corroded Connector.
  • A dirty or stained EGR pintle.
  • A possible failure in the EGR solenoid.
  • Damaged EGR.
  • Broken ECU or faults in the Computer.
  • Short to ground (short circuit).

Easy Diagnosis Of Engine Error OBD Code P045C

If you want to easily diagnose this fault code, then all you have to do is to follow the steps which are mentioned below:

 

An obtrusive and sure sign of this is smoke or steam being exuded from underneath the hood. The ignition timing could be inaccurately set and will require correction and adjustment. If on checking under the hood the driver belts are seemingly loose, they need to be adjusted to be made completely taut or replaced. If you notice any quantity of liquid under the car, it could be an indication that the cylinder head gasket is falling. An unmistakable confirmation for this will be the smoke being expended from the exhaust system. The amendments of the parts and components should solely not focus on P045C. Also, the vehicle service manual should be considered and consulted for information on the potential causes of the fault, along with the testings required.

 

Common Mistakes When Diagnosing the P045C Code

 

Terrified? Don’t know where and how to begin diagnosing? No worries, we at Parts Avatar have listed a few common mistakes that might lead to misdiagnosing the entire problem and causing further complications.

 

  • EGR Valve collapsed.
  • A possible failure in the Powertrain Control Module (PCM).
  • Issues with the Wiring.
