What it means
P0D60 is a generic powertrain code meaning the control unit has found a range or performance problem with the sense (feedback) signal from hybrid or EV battery pack cooling fan 2. The monitoring module compared the fan's commanded speed or state with the feedback it received, and the two did not agree or the signal was outside the expected range. Fan numbering and module layout depend on the vehicle, so check the manufacturer's information for which fan is 'fan 2'.
Symptoms
- Hybrid or EV system warning light or malfunction indicator lamp on
- Audible fan noise that is louder than normal, constant, or missing when it should run
- High battery temperature readings or a warning message after heavy use
- Reduced power or limited regenerative braking and charging
- Reduced charging speed or the car limiting battery use in hot weather
Possible causes
- Blocked or dirty battery cooling fan intake, duct or filter restricting airflow and affecting fan speed feedbacklikely
- Faulty or worn battery cooling fan 2 (seized, noisy or running off-speed)likely
- Wiring or connector fault in the fan's power, ground or sense circuit (corrosion, chafing, loose pin)possible
- Fault in the fan control relay, driver circuit or fan control modulepossible
- Low or unstable supply voltage to the fan, such as from a weak 12 V battery or poor earthpossible
- Outdated or faulty control unit software where a known fault is documented by the manufacturerrare
How to diagnose
- Read all stored codes and freeze frame data, noting battery temperature, fan commands and vehicle state when the code set, and check for other related fan or temperature codes
- Check the health and charge of the 12 V battery, as low voltage can upset fan control and feedback
- Visually inspect the fan intake, ducting and any filter for blockages, debris, pet hair or damage, as the layout varies by model
- Inspect the fan wiring and connectors for damage, corrosion, water ingress and loose pins
- Use a scan tool with bidirectional control to command fan 2 through its speed range, listening for smooth operation and comparing commanded and actual speed values
- Check the fan's supply, earth and sense signal against the manufacturer's wiring information, and test the relevant fuse and relay if fitted
- Check for relevant software updates or technical bulletins for the model before replacing control units
- Clear the code and road test, then recheck that it does not return and that battery temperatures stay normal
How to fix
- Clean or clear the fan intake, ducting and filter, and refit them correctly
- Replace the faulty battery cooling fan 2 and its seals or ducting as the manufacturer specifies
- Repair or replace damaged wiring, terminals or connectors in the fan circuit
- Replace a faulty fuse, relay or fan control module once the cause has been confirmed
- Repair the 12 V supply or earth fault, or replace a weak 12 V battery
- Apply a manufacturer software update if a known calibration fault is documented for the vehicle
Can I keep driving?
The car can usually be driven for a short time, but poor battery cooling can lead to overheating, reduced power and shortened battery life, so have it checked soon. Avoid heavy loads and hot conditions, and stop if a battery temperature or hybrid system warning is shown.
