2013 Ford Escape Overheating Message
Just putting this here in case anyone runs into this. On these Ford Escapes at some point Ford issued a recall for a risk of overheating that could cause a fire. Part of this recall involves installing a new junction box connector that is installed on the battery box.diag.net/file/f2n9ejrri…
The harness is installed between two connectors that contain the Can lines for the coolant level sensor. The connectors of the jumper harness can be plugged into themselves bypassing the juniction box connector. diag.net/file/f2xk1z8qv…
If this happens instead of it telling the driver that coolant level is low it instantly displays a message in the DIC stating the engine is overheating. There is very little information on these codes and because this was an updated harness it also does not appear in any diagrams. If this harness is incorrectly plugged it it also does not effect the reading of the ECT in scan data.
Hope this helps someone so they don't pull their hair out like I did.
Is any of this visible when the car is assembled, or is this underneath something somewhere? Having trouble picturing where any of this goes. Most Ford Escapes out here are 2003-05.
Tanner said that the new junction box is on the battery box.
So are battery temp sensors on old Jeeps....doesn't mean much out of context Ray. IOW, I need to see the thing on the car for the case study to mean anything in my head.
Geoff, the junction box is visible as the battery box is in the front left. The wires attaches to it are pretty long though and not visible when plugged in as they go down behind the battery box.
Hi Tanner. Do you know what years this covers or have the recall number? Thanks, Mike.
Alright thanks. I know you are an instructor, so my feedback, from a student perspective, is I need to see pictures of the parts on the car, not lying on a table. That could be A/M Stereo remote start wires for all I can tell. I remember nearly everything I see on a car. Pictures of parts, in free-space, not so much.
Geoff thank you for that, I will see what I can do.
Also on these if someone gets trigger happy and re-flashes the PCM without reading up, and the recall has not been done you will end up with the same faults.
Yes this is correct, that Flash is what causes this to happen.
Tanner, I was called to a shop that had installed an engine in one of these. I pulled my hair out too. I finally found out they had plugged the jumper harness into itself exactly like you mentioned.
This one went the same way, used engine installed prior.
Thank you for sharing, we have quite a few of these in our fleet. I'll be sure to look out for that.
I replaced a transmission in a 14’ and did this. I eventually found what I did but also found the pids for coolant temperature and coolant level were jiberish when monitoring with data stream.
This one the data was correct. 102 at the time of checking after it ran for 10 min. Went to -40 with ect disconnected. Coolant level did read lower than when fixed but data was still normal.
Tanner I have a 2013 Ford escape 1.6 with a code u1035 TSB recalls have been done I check wiring from the code sensor to the PCM I got power ground and com on the low and high speed bus from PCM to sensor... What's next replace the level sensor as started in the SI what IAM missing
If the pcm was updated and the recall was not performed that will cause your code. The recall has the technician install a jumper harness in the level sensor wiring. check the recall and see if your pcm has been updated or not.
Tanner The update has been done Unfortunately is there a way to check the coolant level sensor/ pipe stand
Has the recall itself been done? If just the flash was done and the harness was not installed you will have this problem. see if that small box is mounted to the battery box.
Tanner Sorry for the confusing brother I was out in the field when texting you, But yes the recall has been on there is a small box mounted by the battery, this was shipped from Copart and drop off at a dealer shop they stated to me the vehicle run for about six hours with not issues. I verify codes and found p0073- p0135-p1299-U0284-U103500 all the codes listed has been fixed but not P1299 and…
Make sure that small box does not have the wires plugged into itself. Basically there is 2 plugs on it and they should not be plugged into each other. I will look more at a diagram tomorrow.
Tanner I verify circuit integrity form the coolant level sensor to the spice box and to the Pcm. Unfortunately they are not plugged into each other on another note i found some information in IDS to verify the coolant level sensor functionality under power train , service functions then coolant level check it shows the engcool canmsg PIDS. youtube.com/watch?v=4ZYvoX…
Thank you, one of my technicians put in a engine and did exactly this if it wasn't for your post I would probably still be testing valves and wires. Thanks again.
If these two connectors are not supposed to be plugged into each other..what do they plug into? Working on a 2013 fusion with the 1.6. I Put a engine in and these two connectors are floating around by the firewall in need of a home
Ford retrofittEd these with a level gauge (mounted near the resevoir on escapes) and a sub harness the plugged in between these two original connectors (located near the battery on the escape). If you changed the engine, check your old for a spare harness as pictured above. It reminded me of a heater core harness.
These connectors go in line of the harness for the coolant level sensor. Basically think of the harness as a T for that harness.
