2.2 i-CTDi engine: faults and reliability

Honda introduced the 2.2 i-CTDi (short for "intelligent Common-rail Turbocharged Diesel injection") in 2003, with the launch of the seventh-generation Honda Accord in Europe. With the engine codes N22A1 and N22A2, it then spread to the eighth-generation Honda Civic, the Honda CR-V (at the end of the second generation and in the early part of the third) and the Honda FR-V. Honda phased it out from 2008, replacing it with the i-DTEC, a related engine with a different code numbering (N22B).^[1][3][7]

It is a 2,204 cc in-line four-cylinder with an aluminium block, twin overhead camshafts in the head and, like its successor the i-DTEC, a timing chain instead of a belt. Injection is common-rail and the turbocharger is variable-geometry, supplied by Honeywell or Garrett depending on the source. Across the range it delivers 140 hp and 340 Nm of torque, meeting the Euro 4 standard.^[1]

This entry covers the 2.2 i-CTDi in the eighth-generation Honda Civic (2006-2011), the seventh-generation Honda Accord (2003-2008), the second-generation Honda CR-V (in its final year, 2005-2006) and third-generation CR-V (2006-2009, before it moved to the i-DTEC) and the Honda FR-V (2004-2009). It does not cover the i-DTEC (N22B), a different engine that replaced the i-CTDi in the Accord and arrived later in the Civic, CR-V and HR-V: see content/engines/honda-i-dtec.json.^{[3][4][5][7][8][9][10][11]}
