International Cv515 Diesel Particulate Sensors

International Cv515 Diesel particulate sensors

Starting at low prices, AutoBuffy stocks multiple diesel particulate sensors from top OE-quality brands. This sensor monitors soot accumulation and exhaust backpressure in the diesel particulate filter (DPF), feeding data to the ECU to trigger regeneration cycles. A failed sensor causes incorrect regen timing, DPF clogging, and can lead to costly filter replacement if ignored.

Signs your International Cv515 needs a new diesel particulate sensor

  • DPF warning light or check engine light illuminated on the dashboard
  • Forced regeneration cycles that run too frequently or fail to complete
  • Noticeable drop in fuel economy due to improper regen triggering
  • Black or excessive smoke from the exhaust during or after attempted regeneration
  • Reduced engine power or limp mode activation caused by DPF over-pressure faults
  • Stored fault codes related to DPF differential pressure, soot load, or sensor circuit failure

Which diesel particulate sensor should you buy for your International Cv515?

The main decision is whether to buy an OEM-equivalent sensor or an aftermarket unit, and whether you need a standalone pressure sensor or a combined pressure-and-temperature sensor assembly. Fitment accuracy is critical — even a small connector or thread difference will prevent proper installation and reliable readings.

OEM-Equivalent (Direct Fit)
Best for
Drivers wanting exact factory replacement with no calibration
What you get
Matched connector, calibrated pressure range, plug-and-play fit
Aftermarket Quality (e.g., top OE-quality brands)
Best for
Cost-conscious owners who still want reliable accuracy
What you get
Lower price point, meets OEM spec tolerances, broad vehicle coverage
Differential Pressure Sensor Only
Best for
Vehicles where temperature sensor is separate and intact
What you get
Monitors upstream/downstream DPF pressure differential to assess soot load
Combination Pressure + Temperature Sensor
Best for
Vehicles using an integrated assembly or when both sensors are faulty
What you get
Single unit handles both measurements, reduces connection points and labor time

Replacing the diesel particulate sensor on a International Cv515

Moderate⏱ 30 minutes to 1.5 hoursOBD-II scanner (for code reading and regen initiation)Combination wrench or deep socket setPenetrating oil (for corroded sensor threads)Electrical contact cleanerSafety gloves and eye protection

Locate the sensor on the DPF housing — typically accessed from underneath or at the side of the exhaust system — and disconnect the wiring harness before unthreading the sensor. Apply penetrating oil to the threads if corroded, and allow time to soak before removal to avoid damaging the housing. After installing the new sensor and reconnecting the harness, clear all stored fault codes and perform a short drive cycle or forced regeneration to confirm the system reads correctly.

Frequently asked questions

How much does it cost to replace diesel particulate sensors on a International Cv515?
Parts start at low prices on AutoBuffy. A professional shop typically adds one to two hours of labor on top of the part cost. DIY replacement keeps costs to the part price alone. Delaying replacement risks DPF damage that costs significantly more to repair than the sensor itself.
Can I drive my International Cv515 with a faulty diesel particulate sensor?
Short trips are possible, but it is not advisable. A failed sensor causes the ECU to mismanage DPF regeneration, leading to soot overloading or unnecessary burn cycles. Prolonged driving with a bad sensor can permanently clog or damage the DPF, turning a minor sensor repair into a major filter replacement job.
Will a bad diesel particulate sensor trigger a check engine light on a International Cv515?
Yes. A faulty diesel particulate sensor almost always stores a diagnostic trouble code and illuminates the check engine or DPF warning light. Common codes relate to pressure sensor circuit faults, signal out of range, or implausible differential pressure readings. Scanning for codes is the fastest way to confirm the sensor is the cause.
Do I need to reset or reprogram the ECU after replacing the diesel particulate sensor on a International Cv515?
In most cases, clearing stored fault codes with an OBD-II scanner after installation is sufficient. A full ECU reprogram is generally not required if the replacement sensor matches OEM specifications. However, some vehicles may require a forced DPF regeneration cycle after the repair to confirm normal system operation.
How long does a diesel particulate sensor last on a International Cv515?
Diesel particulate sensors typically last several years under normal driving conditions, but lifespan varies based on driving patterns, fuel quality, and how often the DPF completes full regeneration cycles. Frequent short trips that prevent complete regen, or low-quality fuel, can accelerate sensor degradation through heat stress and contamination.
What is the difference between a DPF pressure sensor and a DPF temperature sensor on a International Cv515?
The pressure sensor measures differential pressure across the DPF to estimate soot accumulation and signal when regeneration is needed. The temperature sensor monitors exhaust gas temperature to ensure regen burns occur safely and completely. Both sensors work together; failure of either one disrupts the regeneration process and can trigger warning lights.
