P0D62Hybrid/EV Battery Pack Cooling Fan 2 Sense Circuit High
- 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
- P0D62 is set when the feedback of battery cooling fan 2 rises above its plausible maximum. Volkswagen gives the threshold for the 2014 Touareg Hybrid as a fan 2 feedback voltage above 3.45 V, mirroring P0BCA for fan 1. A real fan cannot drive the signal that high, so the cause is electrical: the feedback wire touching a supply or another signal, a missing ground at the fan so the line floats up, or fan electronics stuck at their upper output. Check the ground and the harness routing before condemning the fan. The bottom end of the range is P0D61, while P0D60 covers a valid signal that disagrees with the command. With the speed information unusable, the controller cannot verify cooling and may restrict battery power.
- What you may notice
- Hybrid system warning or check engine light
- Electric power limited when the battery gets warm
- Fan 2 may still run normally
- Likely causes
- LikelyFan 2 feedback wire shorted to a supply or neighbouring signal
- PossibleOpen ground at fan 2 letting the feedback line float high
- PossibleFan 2 electronics stuck at their upper feedback level
- 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.
