<<See All OBD Codes

Hate these discontinuations in your journey? A little learning can always be dangerous! Not with us though. We at Parts Avatar have noted down all the information you need to crack this Error Code P045F. The Exhaust Gas Recirculation systems (EGR) constitutes elements like the EGR Valve, Engine Control Module (ECM), controlled Vacuum Switch Valve or the EGR Solenoid and an EGR Vacuum Modulator. Relying on the Engine and the driving conditions, the ECM controls the EGR Solenoid which operates the EGR Vacuum Modulator to control the opening and closing of the EGR Valve. From the Exhaust Manifold.

The EGR system on the newly built vehicles uses a step motor to regulate the flow rate of EGR from the Exhaust Manifold. The motor has four winding phases, and operates in accordance to the output pulse signal of the ECM. the two windings are turned ON and OFF in sequence. Every time the ON pulse appears, the valve opens or closes, changing the flow rate. Similarly, when no change in the flow is required, the ECM doesn’t issue the pulse signal. A specific voltage signal is issued so that the valve remains fixed at that certain opening.

The Exhaust Gas Recirculation systems (EGR) are used to decrease the combustion temperature, and to reduce emissions. If the Engine Control Module (PCM) fails to record the amount of flow requested from the EGR, it sets the error code P045F.

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

• Damaged EGR valve.
• EGR valve plunger choked by carbon or other harmful debris.
• Broken EGR Control Solenoid/Valve.
• Disconnected or shortened wires/connectors in the EGR B control circuit
• Defective DPFE sensor
• Distorted EGR valve position sensor
• Malfunctioning PCM or error in the PCM programming.

1. EGR - Terrified because of the recurrent appearance of the Error Code P045F? Well, it could be due to a faulty EGR. So, why not get it changed? Order yours now from Parts Avatar delivering top notch products at pocket friendly prices across the country.
2. Engine Control Module - Having problems with the Engine Control Module? Don’t you worry, Parts Avatar has it all. A defective Engine Control Module could end up being the root cause behind the Error code P045F.
3. PCM - A malfunctioning Powertrain Control Module can end up being the chief host inviting the Error Code P045F. So replacing one can be one of the wisest decisions to avoid a problematic system.
4. DPFE - Facing the Error P045F? Well, get that fixed with a new DPFE Sensor. So to further avoid complications get yours replaced/repaired now.
5. Rough engine idle - tired of these halts in the journey? Well, not anymore. Get your Rough Engine Idle replaced now to fight back the Error Code P045F.
6. Freeze frame - Facing the error code P045F? A Freeze Frame can always be hazardous for the system also it is one of the primal causes behind the existence of the error code P045F. So fix yours now.

Here are some steps which you should follow in order to diagnose this fault code:

Visual investigation of all wiring and connectors related to EGR system is an important step in ushering diagnosis of code P045E. change or mend any burned or corroded elements as required. The next step is to connect the scanner to the diagnostic port and recovering all stored codes and freeze frame data. If the code P045E is an intermittent code, it is advisable to write all this down.

Next, clear all codes and test drive the vehicle to check whether the code has been reset. If you discover that the code is reset, connect the scanner and observe the data stream. Attest the required EGR position (usually measured in percentage) and actual EGR position as displayed on the data stream display. Within the fraction of a second, they should appear to be identical. In case the actual EGR position indicates that it is opened too far, it might indicate that a piece of carbon has blocked the plunger opening or that the EGR valve is faulty. The most convenient method for the inspection of the EGR plunger would be to remove the valve and check visually. Unfortunately, the location of the EGR valve on some new models makes EGR valve removal (and reinstallation) quite difficult.

It should be preferred to inspect the EGR valve first if it can be removed easily (particularly if the vehicle in question has more than 100K miles). Carbon fouling and passage blockage are fairly common problems for vehicles which have high mileage. If the plunger appears to be defective, remove the obstruction and test the EGR system again. On further inspection if you do not discover any obstruction in the EGR valve opening, follow the manufacturer’s recommendations for testing the EGR actuator solenoids with the DVOM. step down EGR valves may use numerous solenoids to affect the complete spectrum of EGR system operation. If when the EGR system for the vehicle in observation uses an EGR valve position sensor, it is likely integrated into the valve itself. To test individual elements, follow connector pinout charts and vehicle wiring diagrams found in your vehicle information source as well as the manufacturer’s recommendations.

Replace damaged parts as required and retest the system. The DVOM should be used testify the individual circuits between the PCM Connector and the EGR Valve Connector. Also, one should be cautious and detached from the circuit before the tests begin. The carbon deposits formed due to high level of detergent found in modern fuels should be taken care of and be avoided. Once done with the repairs, allow the PCM to enter readiness mode before assuming they were successful.

Common Mistakes When Diagnosing the P045F Code

Anxious about a misdiagnose? Don't worry! We have listed here a few basic mistakes that’ll help you in staying alert while performing the diagnoses of the Error Code P045F.

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