Its electro viscous - its not a true electric fan, its pulse width modulated (PWM) controlled by the PCM Its still a clutch fan style - only instead of a thermal spring it has the PCM controlling the speed via a VREF circuit -I do not think this is your issue.

for the air issues he has and a shop previously found CO2 in the system. I am going with a leaking EGR Cooler - (Exhaust to Cooling System) - small exhaust pressure pulses entering the cooling system and building up (in the high point) Heater Core then releasing in a sequenced pulse into the...

The question is - (Important) - What is the Scan Tool showing for - Estimated Battery SOC? This PID is the driving factor for the BCM's decision making - to Load Shed, the battery can be 100% charged and sitting at 92 % Plus SOC (Actual) but if the BMS sensor is not accurately reading (Biased)...

Yes - I like it - it works great but STINKS - I hate the smell of it.

yes - this had me puzzled as well - Ford approved an engine assembly for something that can be replaced (head) - even so - with some finesse the plug will come out - you just have to know the tricks - and #1 if the plug shows it's going to fight - STOP - and take a step back and be cautious on...

THIS👆👆 From someone who deals with flight deck - knobs and switches frequently - this helps and most have 2 setscrews to secure the knob. so, picture the shallow space between the knob and the panel - no room for the tool to rotate full travel (360 Deg) - this is where the above step will make...

i wonder if - changing the Target SOC requires the BMS Reset after you do it? or Are you noting that even after this is done - the BMS still will bias and under report? I have a hunch it's the Temperature - altering the readings - and we may see different results in the summer months. (My...

Awesome

Yes, Ford recommends - BMS Reset only with a battery replacement - however they also have in one of their documents to reset the BMS sensor for issues with - Deep Sleep and Deep Sleep ties into the Load Shed. If he was to check the Estimated SOC PID, I am sure he would have saw a biased sensor...

Small Update: I have been periodically monitoring the Live Data and set at 90% Target SOC, at least now (Winter Months) I am staying in the 88 to 94 Percent - Range (Estimated SOC) being that I see it mostly hovering on the 88% mark, I am thinking about bumping the target up to 92% and see if...

C2909A - APIM to USB HUB - The APIM provides the Power & Ground for the HUB, so by your issues - this tells me that the RH Port has a more direct feed back to the APIM and the LH Port is a (Rider) of the RH Port. Have you ever used a - Powered Hub for your computer, plugged into a wall outlet...

Somewhere on here it’s been done - will have to find it - it was done just after Ipone switched there charge port , I think they had to modify slightly to get it to fit

For me I hear an extra noisy HP Fuel Pump, mainly noting the rattle (just off the throttle) but to confirm- listen to the Blow Off Valve & Purge Valve to verify the noise is not coming from those and pay close attention to the HP Pump for the noise - mainly the off throttle rattle - as that is...

Ref post # 20 for a wiring diagram, note (A) connector is Power & Ground for the Hub (Powered Hub) with the hub lights not working, it is indicating a power issue with the hub. So the hub has enough power to feed the RH port but not the LH side - so it’s more than just the USB cable , it’s most...

If the port lights are not working then it’s a power to the port issue and not the USB cable. It’s a powered hub.

I am working on TRYING to find a - Tolerance range for the DPFE, proving difficult to find for our Rangers. It (APPEARS) to be - (+/- 0.30 PSI) So what this means is that your 0.29 reading at KOEO and Idle - will still provide a reading of (+) flow when the EGR Valve Opens - and outside of...

I was thinking on this - and to help isolate clogged tube (Bung) or sensor. Remove the sensor and see if the pressure goes to normal. If it does then the tube is clogged (trapped) pressure. (Leave connector connected)

The more I think about this: Previous (CO2) Test Fail It's not a violent (Press) burp Exhaust Pressure in the (EGR Cooler) closely matches (Cooling Sys Pressures) w/o Turbo and slightly elevated with Turbo-Boost Brings me to the conclusion - it's not the Pistons it's the EGR Cooler - and would...

Yes- The Ex Press sensor should be reading very close to the Barro / Map Pressures @ KOEO, the same as the Barro / Map (Readings) are. The @ idle reading should be (Slightly) above the Barro - 17.2 is too high From idle to 2,000 RPM - the Ex Press - Decreased - It should slightly rise So, the...

The neg test - has me scratching my head as well, But note: How the timing of the (Burps) is approx. every 5-seconds. So, for me - and looking at it this way - A small hairline crack (Piston) Pressure will send - short bursts of air into the cooling system - once the pressure builds - it gets...
