P0068-MANIFOLD PRESSURE/THROTTLE POSITION CORRELATION

When Monitored and Set Condition:
P0068-MANIFOLD PRESSURE/THROTTLE POSITION CORRELATION
When Monitored: With the engine running and no MAP Sensor or TP Sensor DTC?s set.
Set Condition: The PCM determines a valid range in which the TP Sensor should be, at
a given RPM/Load. The actual TP Sensor voltage is then compared to this value. If the TP
Sensor voltage does not fall within the expected range within a predetermined time an
error will be detected. Two Trip Fault.
POSSIBLE CAUSES
GOOD

i had this problem when running 62mm throttle body and safc 2
