What P0D62 means
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.
P0D62 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyMedium
- Typical labor0.5 to 2.5 hours
- Clears after repairAfter a drive cycle
Symptoms of P0D62
- Hybrid system warning or check engine light
- Electric power limited when the battery gets warm
- Fan 2 may still run normally
Common causes of P0D62
- Most 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
- Less likelyFeedback input of the battery control module defective
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0D62 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 62 | The exact fault in that area. |
What to do next
- Note P0D62 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0D62
What does P0D62 mean?
P0D62 means "Hybrid/EV Battery Pack Cooling Fan 2 Sense Circuit High". P0D62 is set when the feedback of battery cooling fan 2 rises above its plausible maximum. It is a generic code, so it means the same on every make.
Is it safe to drive with P0D62?
Drive gently and only to a workshop. With P0D62 the car can go into limp mode (reduced power) to protect itself.
Will P0D62 fail an emissions test?
Yes, it can. P0D62 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P0D62 to fix?
Difficulty: medium. A typical repair takes 0.5 to 2.5 hours of work. This is a job for a workshop.
Will P0D62 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
