P0068 2017 Ford F150 Code - Manifold Absolute Pressure/Mass Air Flow Sensor - Throttle Position Correlation
Quick Answer
The Powertrain Control Module (PCM) monitors a vehicle operation rationality check by comparing the Throttle Position (TP) to Mass Air Flow (MAF) Sensor readings (if equipped) or to the Manifold Absolute Pressure (MAP) Sensor readings (if equipped). Common causes include Air leak at any connection or line of the intake air system components before or after the Electronic Throttle Body (ETB), Leak in the Positive Crankcase Ventilation (PCV) System, Throttle Position (TP) Sensor not seated correctly. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Frequently Asked Questions about P0068 2017 Ford F150 Code
1. What does OBDII code P0068 mean for a 2017 Ford F-150?
P0068 indicates a correlation issue between the Manifold Absolute Pressure (MAP) sensor, Mass Air Flow (MAF) sensor, and Throttle Position (TP) sensor, meaning their readings don’t align as expected.
2. What are common symptoms of code P0068 on a 2017 Ford F-150?
Common symptoms include poor engine performance, rough idling, stalling, decreased fuel efficiency, and the Check Engine Light being illuminated.
3. What causes the P0068 code on a 2017 Ford F-150?
Causes may include a faulty MAP sensor, MAF sensor, or TP sensor, a damaged or dirty throttle body, intake leaks, or wiring/connector issues in the sensor circuits.
4. Can a dirty throttle body trigger the P0068 code?
Yes, a dirty or obstructed throttle body can cause air intake discrepancies, leading to a mismatch in sensor readings and triggering P0068.
5. How do I diagnose the P0068 code on my 2017 Ford F-150?
Start by checking for vacuum or intake leaks, inspecting the MAP, MAF, and TP sensors for damage, cleaning the throttle body, and verifying wiring and connections for faults.
6. Can I drive my 2017 Ford F-150 with the P0068 code?
While the vehicle might still be drivable, doing so can lead to reduced performance, higher fuel consumption, and potential long-term damage, so it’s best to address the issue promptly.
7. How can a bad MAF sensor cause the P0068 code?
A faulty MAF sensor can send incorrect airflow data to the engine control module (ECM), leading to a mismatch with the MAP and TP sensor readings.
8. Can a vacuum leak cause the P0068 code on a 2017 Ford F-150?
Yes, a vacuum leak can disrupt the pressure readings from the MAP sensor, resulting in the ECM detecting a mismatch and setting P0068.
9. What tools are needed to troubleshoot the P0068 code?
You’ll need an OBDII scanner, a multimeter for checking sensor voltages, and possibly cleaning tools for the throttle body and MAF sensor.
10. What are the repair options for a P0068 code on a 2017 Ford F-150?
Repairs may include cleaning or replacing the throttle body, MAF sensor, or MAP sensor, fixing vacuum leaks, repairing damaged wiring, or updating the ECM software if necessary.
