Engine: D22DT 1 compatible injectors From £150

Common Injector Failures on the D22DT

The D22DT engine uses high-pressure common rail diesel injection. Over time, injector nozzles wear, seals degrade, and internal components lose calibration. This leads to a range of drivability symptoms that worsen if left unaddressed. We stock 1 tested replacement injectors for this engine from Delphi.

Vehicles fitted with the D22DT include models from SsangYong. If you are experiencing any of the symptoms below, your injectors may need testing or replacement.

How to Test D22DT Injectors

Leak-off test: Connect clear hoses to the injector return lines and compare fuel volumes at idle. The injector returning the most fuel is likely worn.

Correction values: Use a scan tool to read injector correction (IMA) values. Readings beyond ±3 mg/stroke indicate wear.

Resistance check: Measure resistance across the injector connector pins with a multimeter. Compare to manufacturer specs.
