Error Code P046D: What It Means & What To Do?

<<See All OBD Codes

OBD error code P046D is an OBD-II generic code. Thought its generic, the steps to resolve it might vary a bit depending upon the specific make and model. Your vehicle will flash this OBD error code P046D when it has high voltage detected with the egr sensor circuit “A”. If you wish to know more about this error code, you can through our subsequent sections.

Wondering what this alien word obd P046D actually means? Well, in a layman language we can say that it is code indicating a problem with exhaust gas recirculation sensor “A” circuit. Your vehicle’s EGR system is responsible for reducing the emissions. Now, when your vehicle’s powertrain control module detects that the amount of flow expected from the egr is not as specified, it will flash this error code P046D.

What causes this problem with the Exhaust Gas Recirculation Sensor "A" Circuit Intermittent/Erratic?

• Issues with the egr sensor “A” circuit
• Problematic wiring harness and connectors to the sensor
• Carbon build-up on the egr pintle
• Vacuum shortage in the egr solenoid
• Malfunctioning egr solenoid
• Issues with the egr position sensor
• Damaged or bad differential pressure feedback egr sensor

There is no need to get strained if your OBD Code is still flashing up as we are here at your service. Have a look at our superior variety of Engine parts, EGR Sensors, Engine Control Module, PCM, EGR sensor wirings and much more. Now all your problems would vanish within no time.

Here are some steps which you should follow in order to diagnose this P046D fault code:

Since you already know that obd error code P046D indicates low voltage error with the EGR sensor connector, circuit A. Keeping this in mind, you will need to first of all check for any corrosions, broken terminals or loose connections. If you come across any corrosion, try cleaning it and resetting the connector after that.

Next, discharge the electrical connector and also the EGR. Check the EGR intake and exhaust for any blockage or clogging. Clean the junk as required for the smooth pintle functioning. Also check the egr vacuum lines to the solenoid and replace/repair it if found damaged.

In case you own a Ford, you will need to check the two vacuum hoses from the EGR to the differential pressure feedback EGR sensor, also known as the DPFE in the exhaust manifold rear.

Inspect the hoses for any corrosion. Make use of a screwdriver to remove the corrosion from the hoses and the sensors. This will make it function again.

Common Mistakes When Diagnosing the P046D Code

Few of the common mistakes that you can commit while diagnosing this P046D generic obd codes are listed as follows:

• Failing EGR valve
• Failing Powertrain Control Module (PCM)
• Wiring failures
