The terms, conditions, and details of our warranty vary from product to product. Specific warranty details can be found below.

Tamerx Diesel Products provides a replacement warranty on all of our parts. The duration and mileage limitations of the warranty vary by product and are specified on the product's detail page/item listing.

Please note that the warranty covers replacement of the part and the cost of shipping the replacement part to you only. It does not cover any shop, labor, towing, or any similar or related costs. This is not a "money back guarantee".

If you experience a problem with your part or it is not functioning properly, the correct warranty procedure is to call us at (510) 257-1777 (8:00 AM - 5:00 PM ET Monday through Friday). Be sure to have your order number and/or other relevant order information ready so we can easily locate your order and resolve your issue as quickly as possible. From that point, we will review with you any troubleshooting steps that may need to be taken and other areas or systems that can be checked to rule out external problems contributing to your part's issue. If a replacement is determined to be necessary, we will then arrange for your replacement part to ship out ASAP and issue any necessary return shipping labels and/or documents.

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.

EGR (Exhaust Gas Recirculation) systems are vital to maintaining emissions compliance and engine efficiency. If your Paccar MX‑13 (2017–2023) is showing signs of poor performance or strange behavior tied to emissions control, the OEM 2003641PE EGR Pressure Sensor might be the missing link. This sensor plays a crucial role in monitoring back‑pressure within the EGR system, helping your engine balance airflow and avoid trouble.

Key Functions and Diagnostics:

  • Performs real-time EXHAUST PRESSURE MONITORING, enabling correct EGR valve response and preventing improper valve actuation.

  • Helps control NOₓ levels by feeding accurate sensor data to the ECM for proper combustion adjustments.

  • Detects SENSOR MALFUNCTION OR DEGRADATION, allowing the system to fail gracefully and avoid major damage.

  • Critical in avoiding ENGINE DERATE OR FAULT CODES, as inaccurate readings can trigger warning indicators and limit engine performance.

  • Built to meet PAKKAR OEM STANDARDS, ensuring reliable fitment and calibration in 2017–2023 MX‑13 systems.


Replacing your EGR pressure sensor with the OEM 2003641PE can restore proper emissions control and help your MX‑13 engine run smoothly. If you’re experiencing EGR-related fault codes or reduced power, don’t let a small sensor become a big problem—TamerX Diesel Parts offers OEM-grade solutions to keep your engine working efficiently and cleanly.

The Exhaust Gas Recirculation (EGR) pressure sensor plays a key role in monitoring the flow of exhaust gases being reintroduced into the intake system. When this sensor fails, it can trigger fault codes, rough engine behavior, or even emissions test failures. Diagnosing the EGR pressure sensor correctly can help avoid replacing components unnecessarily and ensures proper function of the EGR system.

Steps to Diagnose an EGR Pressure Sensor

  • Check for Stored Diagnostic Trouble Codes (DTCs)
    Use an OBD-II scanner to check if there are any fault codes related to the EGR system, such as P0401 (insufficient EGR flow) or P0405 (low sensor circuit voltage). These codes can guide the diagnosis.

  • Perform a Visual Inspection
    Examine the EGR pressure sensor and associated vacuum hoses or tubes for damage, carbon buildup, cracks, or disconnections. A clogged or broken pressure hose can mimic sensor failure.

  • Test Voltage with a Multimeter

    • Disconnect the sensor’s electrical connector.

    • Turn the ignition key to the ON position (engine off).

    • Use a multimeter to measure the 5V reference voltage between the power wire and ground.

    • Then reconnect and test the signal wire output while the engine is idling; it should read around 1.0V to 2.0V and increase slightly with engine load or throttle.

  • Compare Live Data Using a Scan Tool
    Monitor the EGR pressure sensor voltage through the live data stream while accelerating the engine. No voltage change or erratic readings may indicate a faulty sensor.

  • Use a Vacuum Pump (If Applicable)
    On some systems, you can apply vacuum to the EGR line manually using a hand-held pump and observe the sensor response on a scan tool. No change = bad sensor.

  • Inspect for Carbon Blockage
    Remove the sensor and inspect its ports. Excessive carbon deposits can clog the passages and give false readings. Clean or replace if necessary.

Testing the EGR pressure sensor doesn’t always require expensive tools—just a multimeter, a scan tool, and some attention to detail. By diagnosing carefully, you can avoid misfires, rough idle, or reduced fuel economy caused by EGR-related faults. Always rule out vacuum leaks, hose clogs, or ECM-related issues before replacing the sensor itself. Regular inspections and cleaning of the EGR system can go a long way in preventing sensor failure.

If clogged, gently clear the sensing port with safe cleaner to maintain signal accuracy.

Fault codes, inconsistent EGR operation, or rough drivability often signal sensor problems.

Incorrect data can lead to poor EGR control, increased emissions, and potential engine damage.

The ECU may over- or under-compensate EGR flow, leading to combustion instability.
