As is the case for the majority of the diesel products sold on Tamerx Diesel Products, your part's warranty is active as soon as you install it. In some other cases, warranty activation is contingent upon you sending us your core (i.e., your old part). Tamerx Diesel Products will provide you a return shipping label for parts that have a warranty with a core return condition. When we have received your core return, the part's warranty coverage begins. We reserve the right to void the product warranty if your core is not received within the allotted time, or if it isn't received at all. If the warranty for the diesel part you are purchasing has a core return requirement, it will be clearly noted on the product detail page/item listing.

What is a Core Charge?

A core charge (also called "core deposit") is similar to the deposit you might pay for a can or bottle of soda and is a standard requirement in the auto parts industry. For example, in many states, to promote recycling, you pay a deposit when you purchase a can of soda and receive your deposit back when you return the empty can. Many automotive parts have a core charge, or core price, that works in essentially the same way as a soda can deposit.

30 Day Core Charge Hold

You authorize Tamerx Diesel Products, to hold your credit card for the specified core charge amount and that you agree to return your core with 30 days of receiving the purchased part. When we have received your core return, the hold is released and the core charge payment is canceled.

When the DEF doser injector malfunctions, it can lead to increased emissions, reduced fuel efficiency, and even engine performance issues. Troubleshooting a DEF doser injector can help you identify and resolve problems early, ensuring your vehicle runs smoothly and remains environmentally compliant. In this blog, we’ll explore the steps to troubleshoot a DEF doser injector effectively.

Steps to Troubleshoot a DEF Doser Injector

Check for Diagnostic Trouble Codes (DTCs)
- Start by using an OBD-II scanner to check for any diagnostic trouble codes related to the SCR system or DEF doser injector. These codes can provide valuable insights into specific issues, such as injector flow problems or electrical faults.
Inspect the DEF Injector
- Visually inspect the DEF doser injector for signs of damage, leaks, or clogging. If you notice any crystallized DEF around the injector, it could indicate a leak or buildup that needs to be cleaned.
Test the Electrical Connections
- The DEF doser injector relies on electrical signals to function properly. Check the wiring and connectors for any signs of wear, corrosion, or loose connections. A multimeter can be used to test the continuity and voltage of the electrical circuit.
Check the DEF Quality
- Poor-quality or contaminated DEF can cause the injector to malfunction. Ensure that the DEF in your tank meets the necessary quality standards and is free from impurities. Contaminated DEF can clog the injector and reduce its effectiveness.
Perform a Flow Test
- To determine if the injector is dispensing the correct amount of DEF, perform a flow test. This involves activating the injector and measuring the amount of DEF dispensed over a set period. Compare the results to the manufacturer’s specifications to determine if the injector is functioning correctly.
Clean the Injector
- If the DEF doser injector is clogged or has crystallized DEF buildup, cleaning it may resolve the issue. Use a suitable cleaning solution to remove any deposits and ensure the injector’s spray pattern is restored.
Consult a Professional
- If you’re unable to identify the issue or if the problem persists after basic troubleshooting, it’s advisable to consult a professional mechanic with experience in SCR systems. They can perform more advanced diagnostics and repairs if necessary.

Troubleshooting a DEF doser injector involves a combination of visual inspections, electrical testing, and flow analysis. By following these steps, you can identify and address common issues that may be affecting your DEF system’s performance. Early detection and repair of injector problems can help maintain your vehicle’s efficiency, reduce emissions, and prevent more costly repairs down the road.

Keeping your DEF doser injector in top condition is key to ensuring your vehicle remains environmentally compliant and performs at its best.

TAMERX DIESEL REVIEWS

It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).
