P2414O2 Sensor Exhaust Sample Error (Bank 1 Sensor 1)
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Needs a drive cycle to confirm a fix
- How the car detects it
- P2414 means the front air-fuel ratio sensor of bank 1 reports a reading that cannot come from real exhaust, usually a lean value caused by air leaking in ahead of the sensor or a sensor that is damaged. VW's January 2014 Golf/GTI data book uses two windows, a signal voltage of 3.10-4.81 V and a sensor signal of 2.5-3.2 V, with a second set near 2.5 V; another engine uses 3.1-4.77 V and 2.5-3.06 V. VW's bulletin 2038575 for the 2013-14 Jetta and Beetle 2.0 found that the catalyst-heating strategy could damage the front sensor, so the ECM is reprogrammed first and the sensor then replaced. GM's 2005 table for the 3.5 L L66 engine sets it when the A/F sensor stays above 2.3 V for 7 s. P2415 is bank 2. Expect a warning light and possibly higher consumption.
- What you may notice
- Check engine light
- Higher fuel consumption or uneven idle
- Ticking noise from an exhaust leak
- Likely causes
- LikelyAir drawn in through a leak ahead of the sensor (manifold, gasket, cracked pipe)
- PossibleFront sensor damaged by the catalyst-heating strategy (VW Jetta/Beetle 2.0, software update)
- PossibleLoose, aged or contaminated air-fuel sensor
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
- Repair
- Medium · Often possible to do yourself.Typical cost: €60 – €500
