I have the same problem. I found out that in 95 chevy used the connector for an OBD-2 system and the PCM for an OBD-1. In order to access the computer you need a scanner that fits the OBD-2 connector and reads the OBD-1 PCM. I called around and either you can take it in (if drivable mine is not) to Knechts and they will scan it for free. Auto zone carries the CP9185 accutron scanner for 250 dollars and if it does not work for some reason you can take it back as long as you don't ruine the package. Other companies make scanners that will work but they all cost 250 or more. Good luck.

The codes should be cleared with a scanner. However, on a 1995 Aerostar, we are talking about an old EEC-IV system. You cannot clear codes on that vehicle with a generic OBD code reader because it is not OBD compatible. You need to get access to a Ford "Star Tester" or an aftermarket scanner that can emulate a star tester.

Codes can also be cleared on that system by disconnecting the negative battery cable, but this is NOT the recommended procedure because disconnecting and reconnecting the battery cable can cause voltage spikes that can damage sensitive computer equipment in your vehicle. If you decide to do it this way, make sure that you leave the battery disconnected for a minimum of 15 minutes before reconnecting the cable.

Hard start

DTC - 15 Engine coolant temp sensor error (low temp indicated)
This is an Diagnostic Trouble code using the OB1 which simply means the check engine light blinking in series at certain intervals.But my thinking says that if you are having trouble wuth any sensor , the ECU or PCU computer will read all kinds of things in error. Try replacing the TCS temperature control sensor.Only 96 and up have a OB2 Diagnostic system
