P2106 and P2135 Fault Codes - 2000 Ford Expedition 5.4L V8 Diagnosis

Model: 2000 Ford Expedition Fault Code: P2106 Posted: 2018-06-29 19:06

I'm experiencing two trouble codes: P2106 and P2135 on my 2000 Ford Expedition with a 5.4L V8 engine. The vehicle won't start in fail-safe mode, and I'm trying to diagnose the root cause. I've checked online resources for P2135 code explanations but need more specific guidance for this model. The ABS light did not come on before the vehicle entered safe mode; it only turns over. My next step is to test the voltage at the throttle body sensor while someone presses the accelerator pedal down. Any advice or troubleshooting steps would be greatly appreciated.

The vehicle won't start in fail-safe mode, which suggests a critical issue with either the throttle position sensor or engine control system.

I'm trying to understand what the codes mean. The vehicle turns over but doesn't start in fail-safe mode. I plan to test the voltage at the throttle body sensor while someone presses the pedal down.

Thanks for your input — this has made my troubleshooting process much clearer. I'll proceed with testing the sensor voltage and update accordingly.
