The ZTech Volvo D13 EGR Pressure Sensor (22172068 / 21976026) monitors pressure in the exhaust gas recirculation system, providing the ECM with feedback for controlling EGR flow rates to optimize combustion efficiency and NOx emissions. Accurate EGR pressure data is essential for maintaining emissions compliance — a faulty sensor causes EGR system faults, increased NOx output, rough running, and potential emissions test failure in Volvo D13-powered trucks.

Q: Which trucks does this EGR pressure sensor fit?
A: Fits Volvo VNL trucks with D13 engines. Replaces OEM part numbers 22172068 and 21976026.

Q: What fault codes does a failing EGR pressure sensor trigger?
A: Common codes include EGR system pressure faults and SPN 412 (exhaust gas recirculation) related codes in Volvo VCADS.

Q: What symptoms indicate a failing EGR pressure sensor?
A: EGR fault codes, increased fuel consumption, rough idle, elevated NOx emissions, and reduced engine power.

Q: Is this OEM or aftermarket?
A: ZTech is a European aftermarket brand manufacturing EGR sensors calibrated to Volvo D13 OEM specifications.

Q: What is included with this sensor?
A: Includes the complete EGR pressure sensor assembly with connector, ready for plug-and-play installation.
