Thank you for your comment. I agree, most newer Ford models come with an Electric Power-Assisted Steering (EPAS) system

Hi, I have a Ford C-max Energi and have been getting the C102D code which is friction in the power steering. Yet, when I'm parked I can quickly move from lock to lock many number of times and cannot generate the C102D code.
Any suggestions? Thanks-
Hi, thanks for the question. That’s a good observation on your part — if you can swing the steering wheel lock-to-lock quickly without resistance while parked, that suggests the mechanical part of the steering (like the rack and column) is likely fine.
The C102D code points more to the sensor detecting too much internal friction, not necessarily something you can feel. On the Ford C-Max Energi, the electric power steering (EPS) system monitors how much effort it thinks is required, and if the readings get out of expected range, it sets that code.
Here are a few things to check:
- Steering torque sensor might be slightly out of calibration or reading incorrectly. Even if you don't feel a problem, the computer might.
- Battery voltage or weak charging system: Low or unstable voltage can affect EPS sensitivity and falsely trigger friction codes.
- Intermittent internal EPS motor issue: Sometimes, the EPS motor can drag slightly under certain conditions (temperature, load), but not all the time.
- Software update: Some Ford models have TSBs (technical service bulletins) that require reprogramming the EPS module to correct false DTCs like C102D.
If it were my vehicle, I'd first have the battery load-tested and the charging system checked, then have a scan tool monitor live data for the steering angle and torque sensor while turning the wheel. If all looks good, it might just need a software update or recalibration.
Let me know if you want me to walk you through any of those steps.

Thanks for the offer to help.
Last year, I was driving with low tire pressure and received the warning, also at the same time received the power steering service warning.
I got the tire leak repaired and the C102D erased and was told it will just come back, which it does,I need to carry a laptop loaded with Forscan when I drive anywhere
I purchased a new battery from advice from a forum, which did not cure my problem.
I would like to try the Forscan Live View oscilloscope feature but cannot find the PID?
Also, the warning chime only seems to sound when I drive on local roads, full of potholes and sunken manhole covers
I had a flexible exhaust pipe installed a month or so befoe, it was just a flexible section, being told it was cheaper, which I guess it was. But, it took ages and there was lot of acetylene cutting going on under the car while I waited, for a couple of hours. Perhaps a wire got burnt.
I have been to 2 local shops without any luck, they just read the codes.-
Thanks for the detailed follow-up, that helps a lot.
From everything you described, a few things are really standing out now:
- The fact that the warning only triggers over potholes and rough roads makes me strongly suspect this could be a wiring or connector issue, not an actual steering rack or motor problem.
- The exhaust work you had done is definitely a clue. If there was a lot of acetylene cutting and heating around the bottom of the car, there’s a real chance a wire, connector, or even part of the EPS harness got damaged, melted, or stressed. Sometimes it's not a complete break — just heat-damaged insulation causing intermittent faults when the car flexes over bumps.
- Buying a new battery was a good call anyway, but since the issue happens mostly over rough roads, that points more to physical wiring or connector damage than just voltage problems.
About the Forscan PID for steering torque sensor:
Unfortunately, not all modules on the C-Max Energi expose the detailed torque sensor readings as a standard PID in Forscan. Sometimes you need the extended license and even then, certain EPS modules only show limited live data. It’s not always available depending on year and exact model.
Here’s what I would do next if it were my car:
-
Inspect the EPS wiring harness, especially around the steering rack, under the battery tray, and along the frame rail. Look for:
- Burn marks
- Melted or brittle wires
- Connectors that look dirty, corroded, or loose
-
Check the grounds: Especially the main body ground straps under the car and any ground points around where the exhaust work was done.
-
Gently tug and wiggle the harness while watching if the Forscan live data shows any sudden steering-related errors or if you trigger the chime.
-
Clear codes and road test — preferably on a rougher road — and watch if any communication faults show up immediately when hitting bumps.
If you find any damage, even if it’s just a suspicious section, it’s worth repairing or replacing it.
Bottom line:
This sounds more like a classic case of wiring damage from the exhaust repair and road vibrations aggravating it — not a motor, rack, or torque sensor failure yet. Shops that only "read codes" won’t find this — you’re already ahead by noticing the pattern.I can help point out the common areas where wiring issues happen on these, if you want to check more closely.

Thanks, I took the vehicle to a shop and asked them to check the wiring and connectors but they found no faults, apparently the loom is nowhere near the flexihose that was replaced. I guess I should get the suspension checked out before I splash out on a refurbed rack?
-
Thanks for the update, Terry. At this point, with wiring and connectors visually checked and no obvious faults found, it is reasonable to start looking at the suspension and steering linkage more closely—especially since the warning tends to trigger over rough roads.
Something like a worn strut mount, a binding tie rod end, or even excessive play in a control arm bushing can cause enough feedback or resistance that the EPS system interprets it as abnormal friction.
Before going all-in on a refurbished rack, I’d suggest:
- Have the front suspension components checked under load, not just with the wheels hanging. Sometimes binding or looseness only shows up with weight on the system.
- Also check for steering shaft U-joint wear, especially in the intermediate shaft. If it’s dry or starting to seize up, it can mimic high friction even though the rack is fine.
- If possible, have someone use Forscan to monitor steering angle and torque sensor readings live while turning the wheel at low speeds and over bumps. Even a quick spike might tell you if it’s a sensor misreading vs mechanical drag.
You're doing the right thing taking it one step at a time. If you don’t feel any stiffness or abnormal steering effort yourself, odds are still good that this is either a sensor interpretation issue or something in the suspension creating extra load. Don’t rush into replacing the rack until you’ve ruled out the simpler stuff. Let me know if you want help checking specific parts or sensor data.

As mentioned, I replaced the battery, had the wiring to the rack inspected and the steering components and I was recommended to take the vehicle to Fords, and was told the rack needed replacing.
Ford's quote for a replacement EPS unit was quite expensive and from what I gathered from the internet, they used reburbished units? So, I found a company here in Montreal that refurbishes racks and was cheaper and offered a 1 year guarantee, as did Ford.
The old EPS unit must have been getting progressively worse because the replacement rack is so smoothe and light and no codes once I loaded the as built eps file which I had saved.-
Terry, that’s a great follow-up and thanks for closing the loop. It really does sound like the EPS unit itself was the culprit, especially since the new rack feels smooth and light and the code hasn’t returned after loading the as-built data. Sometimes the early signs are intermittent and hard to duplicate—especially when it only shows up on rough roads—so it makes sense the problem gradually got worse until the rack had to be replaced.
You made a smart move going with a reputable refurbisher, especially with a warranty. That’s basically the same route Ford would have taken, since dealers typically supply remanufactured EPS racks with updated parts. Saving money while getting the same guarantee is a win.
At this point, you should be in good shape. Just keep an eye on battery voltage and grounds (since the EPS is very sensitive to low voltage), and you should get a lot of good miles out of the new rack. Glad to hear it’s sorted out.
