2.2 i-DTEC 150 (N22B1/B3/B4, from 2008) engine: faults and reliability

Honda 1.6 / 2.2 i-DTEC (N16 / N22B) version

Buy

It is the version with the best reputation in the family: Accord owners consulted by Fiches-auto.fr mostly rate it well, with several cases of more than 200,000 km without major faults. The DPF, EGR and turbo faults documented in the CR-V with this same block appear mainly from 100,000-150,000 km onwards, not early on.[1][2][3]

What changes in this version

The engine with which Honda launched the "i-DTEC" name in 2008 in the Accord, replacing the earlier 2.2 i-CTDi; from the 2010 facelift it also arrived in the CR-V under the same name. Common-rail with piezoelectric injectors and up to five injections per cycle.[4][5][6]

Engine codes of this version: N22B1, N22B3, N22B4.

Faults of the N22B1 engine

The documented engine faults that affect this version and its years, from most to least important.

  1. 1High severityFrequency: CommonTurboTurbocharger failureThe turbo is one of the i-DTEC's components with the most documented faults, in both the 1.6 and the 2.2: there are published cases in the Civic and CR-V (both generations) from 6,000 km to over 290,000 km, with failures ranging from actuator wear to complete breakage.Appears at around 87,000 km
  2. 2Critical severityFrequency: OccasionalTimingTiming chain wear or breakage at high mileageThe i-DTEC uses a timing chain, not a belt, a design that in most cases lasts the life of the engine. Even so, Fiches-auto.fr records documented cases of chain breakage in the Honda CR-V from 145,000 km, with internal damage that in one case forced an engine replacement.Appears at around 145,000 km
  3. 3Critical severityFrequency: OccasionalInjectionDiesel injector wear or failureThe i-DTEC's common-rail piezoelectric injectors can start to knock or fail with wear, especially from 70,000-170,000 km; in one documented case in the Honda CR-V, a seized injector ended up damaging the engine.Appears at around 70,000 km
  4. 4Medium severityFrequency: CommonEmissions controlClogged DPF and limp mode due to failed regenerationsYes: the i-DTEC's diesel particulate filter (DPF) can become clogged if the car mostly does short journeys that do not allow regeneration to complete, lighting its warning light and triggering a limp mode with less power. It is documented in the Civic and CR-V, almost always from 45,000-90,000 km.Appears at around 45,000 km
  5. 5Medium severityFrequency: CommonEmissions controlEGR valve clogged with soot and sensor failureYes: the i-DTEC's EGR valve can accumulate soot and seize, and its sensor or pipe can fail over time. It is documented mainly in the Honda CR-V (2007-2013 and 2012-2019 generations), with cases from 109,000 km.Appears at around 109,000 km
