2004 Explorer Temp Gauge
On a recent trip I noticed the temp gauge was barely above cold. I still had heat but not the normal. About 30 minutes later the check engine light came on.
Any ideas on where to start with this problem ????

The check engine light is probably telling you that the engine is'nt warming up enough to enter 'closed loop' operation which means it's running rich & wasting fuel.
Looks like you need to replace the thermostat.

Many of the chain auto parts stores offer a service of scanning the PCM for diagnostic codes at no charge, some will even provide a print out of the code and possible causes. You want to be sure to get the code, not just the list of possible causes or the salesperson's interpretation of the code. As suggested above, the code should be in the format of P0123 where P designates a powertrain code, the 4-digit number indicates the particular code identifier. If the digit after the P is other than zero that indicates it is a manufacturer-specific code so the vehicle information needs to have been entered correctly to ensure you have the correct code definition.
