Understanding P0046 Code 6.7 Cummins: How to Diagnose and Resolve it

AvatarByCarl Frisch

P0046 is a diagnostic trouble code (DTC) for a turbo/supercharger boost control solenoid circuit range/performance issue on the 6.7L Cummins Turbo Diesel engine. This code indicates that the signal sent to the ECM (Engine Control Module) from the boost control solenoid is either not within its normal operating range or has an abnormal performance. This can result in reduced engine performance, decreased fuel efficiency, and/or increased exhaust emissions. To fix this issue, it may be necessary to replace the faulty boost control solenoid or replace other components that may have been damaged due to this code being triggered.

Automobile: Diagnosing Your P0046 Code 6.7 Cummins

Diagnosing a P0046 code for your 6.7 Cummins engine can be an intimidating task, but with the right information, you can quickly identify the cause of the problem and take steps to correct it. In order to diagnose the code, you must first understand what it is, what its symptoms are and what are some of the most common causes.

The P0046 Code is a diagnostic trouble code (DTC) that indicates a malfunction in your turbocharger wastegate solenoid. This solenoid is responsible for controlling the flow of exhaust gases as they are expelled from your engine, which helps maintain optimal engine performance levels. When this solenoid fails or malfunctions, it can cause your engine to run rough or stall out completely.

Symptoms of a P0046 Code include poor fuel economy, lack of power when accelerating, stalling and sometimes even smoke coming from the exhaust pipes. If left unchecked this issue can cause major damage to your engine so it’s important to address it promptly. Common causes of this code include faulty wiring or connectors, a clogged air filter or dirty intake manifold, an incorrect turbocharger wastegate solenoid valve position or a failed turbocharger wastegate solenoid itself.

Automobile: Troubleshooting Your P0046 Code 6.7 Cummins

Once you have diagnosed that the P0046 code is related to your turbocharger wastegate solenoid, you will need to troubleshoot further in order to determine what exactly is causing the issue. The first step in troubleshooting this issue should be checking the turbocharger wastegate solenoid for any signs of wear and tear or corrosion as these can often be indicators of an impending failure.

The next step in troubleshooting should be testing the voltage output from the wastegate solenoid with a multimeter in order to ensure that it is functioning properly and not sending incorrect signals to your ECU (Electronic Control Unit). If these tests all check out then you may need to replace the entire turbocharger wastegate solenoid itself as it may have simply failed due to age and wear over time.

Automobile: Repairing Your P0046 Code 6.7 Cummins

In order to repair a malfunctioning turbocharger wastegate solenoid on your 6.7 Cummins engine, you will need to replace it with a new one that meets OEM specifications for fitment and function on your particular model year vehicle and engine size/type combination. For this task you will need access to a lift in order to raise up your vehicle safely so that you can access all necessary components underneath without any risk of injury from lying down on hard surfaces or otherwise working in difficult positions while under your vehicle.

Once you have gained access to all necessary components related to the turbocharger wastegate solenoid replacement process, you will need basic tools such as screwdrivers and wrenches as well as some specialty tools such as vacuum testers which help ensure proper connections between all components involved in replacing this part are properly made during installation so that no leaks occur after installation is complete before re-starting your vehicle’s engine again for testing purposes post-repair job completion.
