My Gen 1 3.0 Monty has started to have the Check Engine Light showing.
Not always on at the start and alternating between bright and dim once the car is warmed up.

The ECU code is 14- Throttle Position Sensor, TPS.

None of the suggested performance issues for a TPS fault are happening- car runs well with no hesitation.

Do I need to immediately do the system checks for the TPS or just ignore the Check Engine Light for now?
I have the factory manual showing all the TPS checks.
