The top one with one wire is for the gauge you needed to replace the bottom one with two wire's that one is for the pcm make sure you get a brass tipped one the plastic tipped one crack's. Also inspect the connector going to it if it's corroded you will have to replace that too.I would start by replacing that sensor that's the most likely cause. Let me know how it run's after you replace it there only like 10.
