ECM Data
By connecting the OBD ll scan tool or the Honda PGM Tester to the 16P data link connector (DLC), various data can beretrieved from the EcM The items risted in the tabre berow conform to the sAE recommended practice.The Honda PGM Tester also reads data beyond that recommended bv SAE.understanding this data wirl herp to rind the causes of intermiftent fairures or engine probrems.
NOTE:
' The "operatlng values" given below are approximate values and may be different depending on the environment andthe individual car.' Unless noted otherwise, "at idle speed" means idling with the engiFe completely warmed up, transmissron in park orneutral and the A,/C and all accessories turned off.

Diagnostic
Trouble Code(DTC)
lf the ECM detects a problem, it will store tt as a cocteconsisting ot one letter and four numbers.Depending on the problem, an SAE-defined code{Poxxx) or a Honda-defined code (plxxx) will beoutput to the lester.
lf no problem is detected,
there is no output.
YES
Engine SpeedThe ECM computes engine speed from the signalssent from the Crankshaft Position sensor.This data is used for determining the I|me andamount of fuel injection.

Engine Coolant
Temperature
(ECT)
The ECT sensor converts coolant temperature intovoltage and signals the ECM. The sensor is a thermis-tor whose internal resistance changes with coolanttemperature. The ECM uses the voltage signals fromlhe ECT sensor to determine the amount of iniectedfuel.
With cold engine:
Same as ambient temper

Heated Oxygen
Sensor (HO2S)
{sensor 1)(sensor 2)
The Heated Oxygen Sensor detects the oxygen con-tent in the exhaust gas and sends voltage signals tothe ECM. Based on these signals,lhe ECM controlsthe airlfuel ratio. When the oxygen content is high{that is, when the ratio is leaner than the stoichiomericratio), the voltage signal is lower. When the oxygencontent is low (that is, when the ratio is richer thanthe stoichiomeric ratio), the voltage signal is higher.

Fuel Tube/Ouick-Connect Fittings
Prgcautions
!@@ Do not smoke while working on the fuel
sysiem. K€ep open flames away from your work area.
The fuel tube/quick-connect fittings assembly connectsthe in-tank tuel pump with the fuelfeed pipe. For remov-
ing or installing the fuel pump and fuel rank, it is neces,sary to disconnect or connect the quick-connect fittings.
Pay attention to following:
r The fuel tube/quick-connect fittings assembly is not
heat-resistanU be careful not to damage it during weld-ing or other heat-generating procedures.
. The fuel tube/quick-connect fittings assembly is not
acid-proof; do not touch it with a shop towel which
was used for wiping battery electrolyte. Replace the
fuel tube/quick-connect fittings assembly if it came
into contact with electrolyte or something similar.
. When connecting or disconnecting the fuel tube/quick-
connect fittings assembly, be careful not to bend or
twist it excessively. Replace it if damaged.
A disconnected quick-connect fitting can be reconnected,
but the retainer on the matlng pipe cannot be reused once
it has been removed from the pipe. Replace the retainer
when- Replacing the fuel pump.- Replacing the fuel feed pipe.- It has been removed trom the oiDe.- lt is damaged.

2. Check the fuel quick-connect fittings tor dirt, andclean iI necessary.
3. Hold the connector with one hand and press down
the retainer tabs with the other hand, then pull the
connector off.
NOTE:
. Be careful not to damage the pipe or other parts.
Do not use tools.
. lf the connector does not move, keep the retainer
tabs pressed down, and alternately pull and push
the connector until it comes off easily.. Do not remove the retainer from the pipe; once
removed, the retainer must be replaced with a
new one.

3. Align the quick-connect fittings with the pipe, and
align the retainer locking pawls with the connector

two seconds, and fuel pressure will rise. Repeat two
or three times, and check that there is no leakage in
the fuel supply system.
