    Intake Air Temp Sensor Issues

    OK, here is the other sensor I was referring to (attached). It is labeled as "TCBP (Turbocharger Boost Pressure) / CACT (Charge Air Cooler Temperature) sensor" which is why I'm second-guessing myself now. Can anyone clarify whether my symptoms would be caused by this sensor failing? It's worth...

    Intake Air Temp Sensor Issues

    @Yupster Dog I got a Doorman sensor from the parts store and it came with the new plug end so I spliced it on while waiting for the Ford part. Didn't resolve the issue. Code came back immediately on startup. Put the new sensor in and spliced on the original plug. No dice. How about the other...

    Intake Air Temp Sensor Issues

    @Yupster Dog Ambient temperature is at 73°. Forscan shows the same. Sent from my Pixel 4 using Tapatalk

    Intake Air Temp Sensor Issues

    OK, I pulled ground off of the (obvious) ground leads coming from the loom at the firewall. After starting it up this morning and letting it idle for 10 minutes, i get 20.9v on the sensor wire. Forscan still shows -40 for the IAT. Again, ithink the voltage reading aligns with what Forscan is...

    Intake Air Temp Sensor Issues

    Ok, from what I've been able to find, the sensor sends voltage back to the ECM on the yellow wire. The voltage will spike if the sensor reads a low (cold) temp, and drop when it reads a high (hot) temp coming through the intake. With Forscan showing -40° and my voltage reading of the sensor wire...

    Wastegate flutter at high gear + low RPM

    Thank you! Happy New Year. I'm here to learn and help where I can. Definitely grateful for the community. Sent from my Pixel 4 using Tapatalk

    Intake Air Temp Sensor Issues

    Anyone have a diagram for the wiring loom that goes to the ECM? I'm looking for a ground wire and don't want to strip back too much of the jacket while I'm prodding around. Maybe a ground pinout number on the ECM connector? Sent from my Pixel 4 using Tapatalk

    Wastegate flutter at high gear + low RPM

    Finally got some time to sit down and decided to re-read your post. I noticed you mentioned the tach was pretty active when your symptoms occurred. When was the last time you pulled and inspected your throttle body? The PCV issue would normally only occur under load and be less noticeable in...

    Wastegate flutter at high gear + low RPM

    Is your PCV active when the engine is at idle? You can put your hand on it to feel whether it's the ball is bouncing up and down or get close enough to hear it clacking away. If that's the case, the spring is likely worn out. You can pull it to see if it's gummed up. You can see mine below. I...

    Drivers Power Seat Won’t Move Forward

    Excellent point. I forgot to mention to the OP that if you push the button you should hear the relay "tick" before the seat moves. If it ticks, but doesn't move then you likely have something jamming the rails/sliders. If it doesn't make a sound then the switch is bad. Sent from my Pixel 4...

    Drivers Power Seat Won’t Move Forward

    Have you checked your switch? You might need a new one. You can use a multimeter to test the pins for voltage if you know how, otherwise buy the motorcraft part SW7259 (14A701) for around $40. I had to replace mine not too long ago. Be careful removing the buttons from the old switch as you will...

    Intake Air Temp Sensor Issues

    Good point. When I stop this evening I will test again using a ground in the same harness and report back. If the numbers in Forscan are correct though I'm not sure what it's trying to tell me... Sent from my Pixel 4 using Tapatalk

    Intake Air Temp Sensor Issues

    I got the PO113 code with the rough, idle/lean condition and rough acceleration symptoms a few days ago. This came after changing my defective PCV which smoothed things out considerably. The code is accompanied by several misfire codes that change cylyinders at random (Mode6 shows random counts...

    Help engine rough idle and stalls out

    SOME BACKGROUND: The vehicle has 114K on it. I bought it about 4500 miles ago and changed out the (original) plugs and coils which had some pretty solid coking. The exhaust also had a lot of carbon buildup, so I am assuming the lean condition was not recent. after running injecter cleaner...

    Rumble strip noise

    I'm not as familiar with the '18s, but could it be misfiring? Does it do it under load? How's the idle? I know you said it's hard to duplicate, but were there any conditions that were the same during each occurence (wet weather, AC/Heater on, cruise control on, etc.)?

    Help engine rough idle and stalls out

    Going to jump on this thread instead of starting another. I also have PO113 with the rough, idle/lean condition and rough acceleration symptoms. The code is accompanied by several misfire codes that change cylyinders. New plugs, new coils, weephole, etc. already done. to solve the problem I...
