2016 F-Type S
60,000mi

Girlfriend just purchased the above car. Got it home and hooked my code reader up. Instantly triggers P0126 no fault lights on car. When i go to live data collant temp looks good climbs in temp and falls as it should when driving. There was a slight hint of collant smell under hood but no visible leaks anywhere.

Any suggestions as where to start looking kinda puzzled as live data was reading good and no fault lights.

Thank you for any insight

 

To save others looking it up, P0126 is a generic code for Insufficient Coolant Temperature For Stable Operation.
My guess is the thermostat is stuck open (not allowing the coolant to heat up), at 60,000 miles a failed thermostat is not uncommon on the F-Type V6 and V8.
Either that or a faulty coolant temp sensor.

 

That is what I was thinking but when she was driving I was monitoring live data. Collant temp would climb up to about 225°F then fall back down. Unsure if there is a secondary temp sensor? Agree looks like temp sensor but how am i reading good coolant temp?

Additional does anyone know proper operating temp when Tstat should open?

 

Yep, a bit of a head scratcher.
Have you tried clearing the code(s) then resetting the electrical system (by disconnecting the earth/ground lead which runs from the negative terminal of the battery from where it bolts to the floor of the trunk) for 30 seconds or so, then reconnect?
Lots of electrical system gremlins can be fixed this way and that may be all you have, a gremlin, so worth a shot.

 

i have been clearing or trying to via Bluedriver code reader. I will give your suggestion a try first thing tomorrow when i go by her place.

 

Your girlfriend has exceptional taste in cars. Better marry her.

 

Have to admit I was very impressed with the car. The preformance from that V6 was amazing. She has absolutely challenged me with vehicle maintenance. Her last vehicle was BMW. Learned to absolutely hate BMW....lol.

Honestly debating on picking up a F-type R for myself

 

Make sure you reset the battery or verify the car is still going in to sleep mode after connecting the generic code reader...Or your battery will be drained.

DC

 

The clue to sleep mode is that the light in the hazard switch goes out after a few minutes (15?)

 

As to coolant leaks:
Inspect the pipe that runs between the banks in the back of the motor that feeds the heater. Was updated in 2019?
Also use a borescope to look under the super charger and behind the water pump. The two pipes that come out, up and around heading to the thermostat have been updated.
The seals for the pipe running from the water pump to the oil cooler under the super charger are known to leak.
Also inspect the area around the little plastic pipe that pokes into the water pump. This is a one shot deal press fitting that can fail.
And finally, the overflow hose running to the reservoir is know to fail.

 

Which 'Fault light are you referring to? I had problems with the battery on my '17 coup dropping after connecting different readers.
A little hazy on the car now as I sold my '17 and am waiting to replace it with a 20-21 Conv.

 

The red triangular HAZARD indicator, directly above the 4-way flasher/hazard switch. Middle of the dash, just forward of the shifter.

 

New here to the forum, and was curious if you have found and corrected your vehicle concern?
