Please let me know what y'all think so I can fine-tune it before replacing the link in our FAQ post. Thanks! --------------- Checking trouble codes on the OBD-I system used in our trucks from 1988 to 1995 is easy and requires no tools other than a paper clip or small scrap of wire for jumpering the A & B terminals on the DLC http://www.chevytalk.org/fusionbb/showtopic.php?tid/273660 connector (also known as ALDL) under the driver's side of the dashboard. Here's a picture indicating the A & B terminals at the top right: ● With the ignition switch off, jumper the A & B terminals on the DLC connector. ● Turn the ignition switch on (but do not start engine) while watching the "Service Engine Soon" light on the dash. ● Each code will be represented by the SES light flashing, pausing, and flashing. ● Normal operation begins with code 12, represented by a flash, pause, flash flash indicating "1" and "2" meaning "12". ● Each code will appear 3 times before moving on to the next. Codes display in numerical order. ● When the list of codes has completed, the list will repeat, starting again with 12. ● Code 12 is normal and not an indicator of a problem. Please note that a code is a starting point and does not necessarily mean the particular sensor or system is bad. Codes can often be caused by other problems and the particular sensor is merely reporting that its data is out of range; it is up to the troubleshooter to determine the cause of the problem. Co

The ECM uses the information from this sensor to help calculate fuel delivery and spark timing. If it's necessary, it will also activate the cooling fans. Fault Code Description 15 - Engine Coolant Temperature sensor error (low temp indicated)—open coolant temp sensor circuit Symptoms Engine running too rich (hard starting or black smoke from exhaust) The engine cooling fan may run constantly Common Problems A failed coolant temperature sensor is the most common cause of a Code 15 A quick test for the coolant temperature sensor circuit from the ECM would be to unplug the temp sensor and watch the coolant sensor reading on the scan tool while jumping the harness side of the sensor connector. The scan readings should switch from full cold to full hot when inserting and removing the jumper from the con
