Need help with Code 34 SES

I am getting an illuminated Service Engine Soon light about 5 seconds after starting my car. Ambient temp about 50 degrees. I am reading a code 34. I have a 92 LT1. Can I get some assistance?
Thanks

My information shows code 34 as MAP sensor, signal voltage low. I know some parts stores can test the sensor.

You are much more likely to have a problem with the connector or wiring than a bad sensor.
