    Sudden death

    Did the voltage drop test but all were healthy. Unplugged the maf, but also nothing changed. Forscan sees spark, fuel injecting, healthy battery voltage, and rpm. However, when the engine stalls, forscan says "unable to read data. Please switch ignition to on", which I assume is pcm...

    Sudden death

    Update: I solved the shorting PSP and OPS wiring and renewed the entire harness branch. Now the truck always starts but dies immediately. When it dies, the dash throws out some random lights and codes, but then seems to reset, and the fuel pump begins priming again, all that without moving or...

    Sudden death

    Thanks for asking. I sent it to an electrician eventually after running out of tests. He found the PSP switch wiring to be causing a short circuit in the harness, and said harness is connected to the main engine harness. After he insulated the wires and removed the bad connector, the truck...

    It’s making me crazy codes after diagnosis advance trac

    Maybe, but also have to check the wiring, maybe there's an open or a short. Or the sensors you picked up have an issue.

    It’s making me crazy codes after diagnosis advance trac

    You're welcome! In this case the best option is to just replace the sensor and hope the fault disappears.

    It’s making me crazy codes after diagnosis advance trac

    For that C1281 code, you have to check the ABS module's main connectors for any corrosion or dirt, and also check the yaw rate sensor's connector for any damage or moisture. If all wiring and connectors are clean, you will probably need to replace the sensor, then clear codes and test drive. If...

    Sudden death

    Was driving on a main street when I hit the brakes for an oncoming speed bump. Car was driving completely fine with zero issues. Suddenly, as I'm braking, the engine turned off, all dash lights came up, and the brakes locked up. The most prominent thing was the small dash screen showing "PRNDL...

    Loosing VSS signal causing speedometer non-op and shifting issues

    Not the same gen, but I had a speedo that played around randomly and a flashing O/D off light (trans in limp mode) after a rebuild. I had to change both the shaft speed sensor and its connector. Make sure the hole into which the sensor is dry and fully cleaned of any debris, and only apply oil...

    Cold Water Leak

    Since the leak stops when hot, I'd assume that's because of expansion, so the most appropriate candidates would be rubber seals or hoses. I never had water leakage, but I did have a vacuum leak from the PCV hose elbow that disappeared when the engine warmed up. Not an expert in water leaks, just...

    5.4 triton vs the 3.5 Ecoboost?

    Having owned a 5.4 2v for a good time now, what I can say is that the v8 is amazing. Tons of low end torque, pretty reliable if taken good care of (over 300k miles on mine), and is pretty straightforward to work on. The fuel economy is decent on highway cruises for a v8 (around 15mpg) but it...

    03 Expedition 4x4 Issue

    I have an 03 eddie bauer 5.4 with 4x4. It had a trans repair a good while now and after the repair 4hi stopped working, but 4lo and A4WD work fine. I got no contact with the previous owner who did the repairs nor the mechanic, so can't get the issue from them. There are no fault codes for the...
