P0068 2002 FORD F150 - Manifold Absolute Pressure/Mass Air Flow Sensor - Throttle Position Correlation
P0068 2002 FORD F150 Possible Causes
- Faulty Mass Air Flow (MAF) sensor
- Large vacuum leak
- Leaking air duct system
- Mass Air Flow (MAF) poor electrical connection
- Manifold Absolute Pressure (MAP) poor electrical connection
- Faulty Manifold Absolute Pressure (MAP) sensor
- TP sensor not seated properly
- Faulty Throttle Position (TP) sensor
First diagnose P0068 2002 FORD F150 code
Check the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded terminals.
P0068 2002 FORD F150 Tech NotesDrive vehicle and exercise throttle and TP sensor in all gears. A TPNS PID less than 4.82% (0.24 volt) with a LOAD PID greater than 55% or a TPB V PID greater than 49.06% (2.44 volts) with a LOAD PID less than 30% indicates a hard fault
Cost of diagnosing the P0068 2002 FORD F150 code
Labor: 1.0The cost of diagnosing the P0068 2002 FORD F150 code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour.
When is the P0068 2002 FORD F150 code detected?The Powertrain Control Module (PCM) monitors operation rationality check by comparing sensed throttle position to mass air flow readings
P0068 2002 FORD F150 Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Lack/Loss of power
- Engine rough idle
P0068 2002 FORD F150 MeaningThe Powertrain Control Module (PCM) monitors a vehicle operation rationality check by comparing Throttle Position (TP) to Mass Air Flow (MAF) readings. If, during a self-test, the comparison of the TP sensor and MAF sensor readings are not consistent with the calibrated load values, the test fails and a diagnostic trouble code is stored in continuous memory.
