DTC P1122: Throttle Position Sensor Signal Higher Than Expected
WARNING: This page is about a different car, the 2003 Acura 3.2TL and 2003 Acura 3.2CL. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
TP sensor is part of throttle body and not serviced separately.
Turn ignition switch on. Using scan tool, check TP sensor data. If throttle position is 16.9 percent or less when throttle is fully closed, problem is intermittent. System is okay at this time. If throttle position is not as specified, replace throttle body.
