DTC P1121: Throttle Position Sensor Signal Lower Than Expected: MDX

Turn ignition switch on. Using scan tool, monitor TP sensor. If throttle position is 16.1 percent (0.8 volt) or more when throttle is fully opened, problem is intermittent. System is okay at this time. If throttle position reading is not as specified, replace throttle body.
