3. Inspect the connector and socket terminals to be sure they are all making good contact.
- If the terminals are bent, loose or corroded, repair them as necessary and recheck the system.
- If the terminals look OK, go to step 4.
4. With the connector still disconnected, make these input tests at the appropriate connector.
- If any test indicates a problem, find and correct the cause, then recheck the system.
- If all the input tests prove OK, go to step 5.
5. Reconnect the connectors to the under-dash fuse/relay box, and make these input tests at the connectors.
- If any test indicates a problem, find and correct the cause, then recheck the system.
- If all the input tests prove OK, the MICU must be faulty; replace the under-dash fuse/relay box.

Actual Mileage and EPA Fuel Economy Estimates Comparison.
Fuel economy is not a fixed number.
It varies based on driving conditions,
driving habits and vehicle condition.
Therefore, it is not possible for one
set of estimates to predict fuel
economy precisely for all drivers in
all environments.
