OBD-II Code

P0695

Severity

Not yet reviewed

Nobody on our side has assessed this code yet, so we are not going to guess at how serious it is.

Can you drive it

We cannot say

Treat it as unknown until a shop reads it with live data. If the check-engine light is FLASHING, stop driving as soon as it is safe to — that means an active misfire, whatever the code.

Indicative cost (USD)

$30–$200

From this code's diagnostic notes. Varies by vehicle, diagnosis, parts, and local labor. This is not a repair quote.

P0695 is Fan 3 control circuit low.

How a shop works this

Work from evidence to part, not the other way round. A code names a circuit or a symptom; it does not name the part that failed.

  1. Note every code that is set, not just this one.

    Codes that appear together usually narrow the cause faster than any one of them read alone.

  2. Read the freeze frame — the conditions the fault was recorded under.

    Cold or warm, idle or load, road speed and engine speed. A fault that only appears cold is a different fault from one that only appears under load, even with the same code on the scanner.

  3. Confirm the fault is current rather than history.

    Clear the code and see whether it returns under those same conditions. A code that does not come back may have been logged during a repair, a flat battery, or a bad connection that has since been disturbed.

  4. Then follow the diagnostic notes further down this page, in the order they are written.

    They are written in the order a shop works this code, cheapest checks first. Where they name a component, inspect its wiring and connector before replacing it.

If the code comes back after a repair, the underlying fault is still there. That is the point to bring in a scanner with live data and freeze-frame, or a shop that has one.

Common symptoms

Read the full diagnostic procedureP0695 is Fan 3 control circuit low.

P0695 is Fan 3 control circuit low. Fan 3 only exists on triple-fan applications or on dual-fan platforms where the PCM treats high-speed as a third discrete output (Ford 3-relay primary/secondary/high).

Cheapest-first ladder

  1. key-on engine-off, identify which physical relay or FCM output the PCM has mapped as fan 3 (verify against the wiring diagram before testing - on Ford 3-relay setups fan 3 is the high-speed series-parallel switching relay; on GM full-size SUV triple-fan setups fan 3 is the third condenser fan added for trailer-tow packages).
  2. Unplug the relay and measure resistance across the relay coil (50 to 90 ohms typical); a shorted coil reads under 10 ohms and confirms the relay.
  3. Check the PCM control wire for a short to ground at battery voltage; 0 V uncommanded means the wire is grounded between PCM and relay.
  4. With a scan tool fan-on command, expect 0 V on the control wire (low-side driver pulling to ground), current draw 5 to 30 A momentary inrush settling to 8 to 20 A steady on the high-speed parallel configuration where both fans run at full battery voltage, and less than 0.3 V drop across the power feed under load.
  5. Expensive-misdiagnosis caveat: fan resistor packs are the common consumable on multi-speed fan systems.
  6. Ford, GM, and Toyota all use 3-step fan resistor packs that burn open at the high-current stage; on Ford 3-relay setups (which mimic a 3-step pack with discrete relays instead of resistors) the high-speed relay itself is the consumable - it's the one that switches the parallel-series configuration and sees the highest contact load, burning the contacts and dropping out intermittently.
  7. Replace the relay, $30 to $60, not the whole fan module.

  • 2003-2010Ford Crown Victoria/Town Car/Marauder Panther-platform uses a 3-relay primary/secondary/high cooling fan setup; P0695 is the high-speed relay 80% of the time, $30 to $60 relay.
  • 2007-2014GM Silverado/Tahoe/Yukon trailer-tow package vehicles get an auxiliary third condenser fan; P0695 here is the auxiliary fan relay or chafed harness at the radiator support, $35 to $90.
  • 2007-2017Toyota Sequoia/Tundra V8 (3UR-FE) uses dual fans through a 3-step resistor pack and a high-speed bypass relay; P0695 specifically points to the bypass relay or the pack high-stage open, $50 to $120.
  • 2008-2015Honda Odyssey J35 V6 doesn't typically have a fan 3 output, so P0695 on a Honda points to PCM software flagging a phantom output - reflash to latest calibration before chasing wiring.

Estimated repair$30 to $200.
