DTC-22 Throttle Position Sensor Error (signal low)

[metransue]

The "Service Engine Soon" light on my '93 Bonneville has been off and on recently the DTC says my problem is the Throttle Position Sensor. The car's running great but the SES light comes on almost always at start-up, sometimes it goes out when driving normal highway speeds and usually comes back on when slowing down and idling. Sometimes it stays on constantly.

Anyone have any experience with this? Since the car's running great am I pushing my luck by ignoring the SES light or should I spend the $56 and replace the sensor now and hope that takes care of the SES warning?

Thanks for any suggestions,
Mark

The code is there for a reason you could check it on a scanner or use the method at autozone.com, repair guides, register and go to engine controls.
