1. Ecm
Hint: each ecm terminal's standard voltage is shown in the table below.
In the table, first follow the information under "condition".
Look under "symbols (terminal no.)" For the terminals to inspected. The standard voltage between the terminals is shown under "specific condition".
Use the illustration above as a reference for the ecm terminals.

1. INSPECT FUEL PUMP
(a) Inspect fuel pump resistance.
(1) Using an ohmmeter, measure the resistance
between the terminals.
Standard resistance
(b) Inspect fuel pump operation
(1) Apply battery voltage to both the terminals.
Check that the pump operates.

Catalyst System Efficiency Below Threshold
MONITOR DESCRIPTION
The ECM uses the sensors mounted in front of and behind the three-way
catalyst (TWC) to monitor its
efficiency. The first sensor, an Air Fuel ratio (A/F) sensor, sends pre-catalyst
A/F ratio information to the
ECM. The second sensor, a heated oxygen sensor (O2S), sends ...
