Solved: Nissan Qashqai 1.5 dCi P0544 / P0545 Error Code Fix (EGT Sensor 8200921749)

Introduction: The "Check Injection System" Nightmare

Are you driving a Nissan Qashqai (J10/J11), Renault Megane, or Dacia Duster equipped with the widely used 1.5 dCi diesel engine?

If you are experiencing sudden power loss, the dreaded "Check Injection System" warning light, or your vehicle has entered Limp Mode (won't rev above 3000 RPM), you are likely dealing with the infamous P0544 or P0545 error codes.

While these codes can be alarming, the culprit is usually a single, specific component: the Exhaust Gas Temperature (EGT) Sensor.

In this guide, we will explain exactly what these codes mean, where the sensor is located, and why replacing it with [High-Quality EGT Sensor 8200921749] is the only permanent solution.

 

Update (Jan 2026): We have confirmed that this P0544 error on the 1.5 dCi engine is most commonly caused by a faulty Upstream EGT Sensor.

The Diagnosis: What Do P0544 & P0545 Mean?

These diagnostic trouble codes (DTCs) indicate a communication breakdown between your car's ECU (Engine Control Unit) and the temperature sensor located on the exhaust line.

  • P0544: Exhaust Gas Temperature Sensor Circuit Malfunction (Bank 1, Sensor 1).

  • P0545: Exhaust Gas Temperature Sensor Circuit Low.

Common Symptoms across Nissan, Renault & Dacia:

  • Limp Mode: The ECU restricts engine power to protect the Turbocharger from potential overheating.

  • DPF Issues: Particulate Filter regeneration stops working because the ECU cannot verify exhaust temperatures.

  • Failed Emissions Test: You may fail inspection due to high emissions.

Pro Tip: If your scan tool doesn't show P0544 but you still have power loss, a faulty [Mass Air Flow (MAF) Sensor] is another common cause for acceleration issues in Nissan engines.

Location: Where is Bank 1 Sensor 1?

Many owners struggle to find this part because it is tucked away. On the 1.5 dCi engine (K9K platform):

  • It is located on the exhaust manifold, specifically Pre-Turbo (upstream).

  • It looks like an L-shaped probe screwed directly into the manifold.

  • Don't confuse it with the O2 sensor. This sensor is specifically for monitoring exhaust gas temperature (EGT) to protect your Turbo and DPF system.

The Solution: Why Cleaning Rarely Works

We often see forum posts asking: "Can I just clean the EGT sensor to fix code P0544?"

The short answer is No.
Unlike MAF sensors which get dirty with oil/dust, EGT sensors fail due to internal thermal stress. The extreme heat cycles of the diesel engine eventually break the delicate internal wiring (thermistor) inside the probe. Cleaning the outside will not fix a broken internal circuit.

The Fix: You must replace the sensor.
Specifically, you need the sensor matching OEM number 8200921749.

Why choose our Aftermarket Solution?

  • Upgraded Probe Material: Designed to withstand higher peak temperatures than the factory original.

  • Direct Fit: Matches the plug shape for Nissan Qashqai J10/J11, Dacia Duster, and Renault Clio/Megane perfectly.

  • Cost Effective: Solves the issue for a fraction of the dealership price.

Warning: Prolonged driving with a broken EGT sensor can cause the ECU to dump excess fuel, which may damage downstream components like the [Nitrogen Oxide (NOx) Sensor]. Fixing the EGT promptly saves you money in the long run.

Compatibility Checklist (1.5 dCi Engines)
