P0D61Hybrid/EV Battery Pack Cooling Fan 2 Sense Circuit Low
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- P0D61 reports that the feedback signal of battery cooling fan 2 sits at or near zero. In Volkswagen's 2014 Touareg Hybrid the battery controller sets it once the fan 2 feedback voltage drops below 0.1 V; the matching fan 1 code is P0BC9. Such a flat reading comes from a feedback wire shorted to ground, a feedback stage inside the fan that has failed low, or a fan that has no supply and therefore produces no signal at all. Unlike P0D60, where a valid signal merely disagrees with the command, here the value is simply out of range at the bottom; the opposite end is P0D62. Because the controller cannot tell whether fan 2 still moves air, it may treat the cooling as lost and limit battery power under load or in warm weather.
- What you may notice
- Hybrid system warning or check engine light
- Fan 2 audibly silent although battery cooling is requested
- Reduced electric power, especially in warm conditions
- Likely causes
- LikelyFan 2 feedback wire chafed through and shorted to ground
- PossibleFan 2 without supply (fuse, relay or supply wire), so no signal is generated
- PossibleFeedback output of the fan 2 electronics failed low or motor seized
- RareFeedback input of the battery control module defective
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
