Intermittent failure, system is OK at this time.

Check for poor connections or loose terminals at
the primary HO2S (Sensor 1), the secondary HO2S
(Sensor 2) and the PCM.

3. Turn the ignition switch OFF.

4. Disconnect the HO2S (primary or secondary )

(Sensor 1 or Sensor 2 ) 4P connector.

5. At the HO2S side, measure resistance between

HO2S 4P connector terminals No. 3 and No. 4.

Go to step 6.

Replace the primary HO2S (Sensor 1) or

secondary HO2S (Sensor 2) .

6. Check for continuity between body ground and

HO2S 4P connector terminals No. 3 and No. 4
individually.

Replace the HO2S (primary or secondary )

(Sensor 1 or Sensor 2 ).

Go to step 7.

7. Start the engine.

8. Measure voltage between HO2S 4P connector

terminals No. 3 and No. 4.

Go to step 9.

Go to step 12.

9. Turn the ignition switch OFF.

10. Disconnect PCM connector B (24P) (PCM connector

E, 31P) .

11. Check for continuity between PCM connector

terminal B5 (E2) and body ground.

Repair short in the wire between the PCM

(B5, E2 ) and the HO2S (primary or secondary )
(Sensor 1, Sensor 2 ).

Substitute a known-good PCM and recheck

(see page 11-5). If the symptom/indication goes
away, replace the original PCM.

12. Measure voltage between HO2S 4P connector

terminal No. 4 and body ground.

Go to step 13.

Repair open in the wire between the primary

HO2S (Sensor 1), secondary HO2S (Sensor 2) and
No. 6 ECU (PCM) CRUISE CONTROL (15A) fuse.

13. Turn the ignition switch OFF.

14. Reconnect the HO2S (primary or secondary )

(Sensor 1, Sensor 2 ) 4P connector.

15. Disconnect PCM connector B (24P) (PCM connector

E, 31P) .

16. Turn the ignition switch ON (II).

17. Measure voltage between PCM connector

terminals B5 (E2) and A5.

Substitute a known-good PCM and recheck

(see page 11-5). If the symptom/indication goes
away, replace the original PCM.

Repair open in the wire between the PCM

(B5, E2 ) and the HO2S (primary or secondary )
(Sensor 1, Sensor 2 ).

DTC Troubleshooting (cont’d)

Fuel System Too Lean

Fuel System Too Rich

NOTE: If some of the DTCs listed below are stored at
the same time as DTC P0171 and/or P0172,
troubleshoot those DTCs first, then recheck for P0171
and/or P0172.

P0107, P0108, P1128, P1129: Manifold Absolute
Pressure (MAP) sensor
P0135: Primary Heated Oxygen Sensor (Primary HO2S)
(Sensor 1) heater
P0137, P0138: Secondary Heated Oxygen Sensor
(Secondary HO2S) (Sensor 2)
P0141: Secondary Heated Oxygen Sensor (Secondary
HO2S) (Sensor 2) heater
P0401, P1491, P1498: Exhaust Gas Recirculation (EGR)
system
P1259: VTEC System

1. Check the fuel pressure (see page 11-216).

Go to step 2.

Check these items:

• If the pressure is too high, check the fuel

pressure regulator, and the fuel return line.

• If the pressure is too low, check the fuel pump,

the fuel line, the fuel filter, and the fuel pressure
regulator.

2. Start the engine. Hold the engine at 3,000 rpm with

no load (in Park or neutral) until the radiator fan
comes on.

3. Check the primary HO2S (Sensor 1) output with the

scan tool or the HDS.

Replace the primary HO2S (Sensor 1).

Go to step 4.

4. Turn the ignition switch OFF.

5. Connect a vacuum pump to the EVAP canister

purge valve on the EVAP canister side.

6. Disconnect the EVAP canister purge valve 2P

connector.

7. Start the engine.

Check the valve clearances, and adjust if

necessary. If the valve clearances are OK, replace
the injectors.

Is f uel pr essur e OK ?

Does it stay at less than 0.3 V or mor e than 0.6 V ?

Is ther e vacuum on the gauge?

03/07/29 09:21:24 61S0X050_110_0132

Replace the EVAP canister purge valve.

Symptom

Procedure(s)

Also check for:

11-133

Random misfire and any combination of the following:

No. 1 Cylinder Misfire Detected

No. 2 Cylinder Misfire Detected

No. 3 Cylinder Misfire Detected

No. 4 Cylinder Misfire Detected

No. 5 Cylinder Misfire Detected

No. 6 Cylinder Misfire Detected

NOTE:

• If the misfiring is frequent enough to trigger detection of increased emissions during two consecutive driving cycles,

the MIL will come on, and DTC P0300 (and some combination of P0301 through P0306) will be stored.

• If the misfiring is frequent enough to damage the catalyst, the MIL will blink whenever the misfiring occurs, and DTC

P0300 (and some combination of P0301 through P0306) will be stored. When the misfiring stops, the MIL will remain
on.

1. Troubleshoot the following DTCs first if any of them were stored along with the random misfire DTC(s):

P0107, P0108, P1128, P1129: Manifold Absolute Pressure (MAP) Sensor
P0131, P0132: Primary Heated Oxygen Sensor (Primary HO2S)
P0171, P0172: Fuel System
P0335, P0336: Crankshaft Position (CKP) Sensor
P0340, P0341, P0365, P0366: Camshaft Position (CMP) Sensor A/B (’03-04 models)
P0401, P1491, P1498: Exhaust Gas Recirculation (EGR) System
P0505: Idle Control System
P1259: VTEC System
P1361, P1362, P1366, P1367: Top Dead Center (TDC) 1/Top Dead Center (TDC) 2 Sensor (’99-02 models)
P1519: Idle Air Control (IAC) Valve

2. Test-drive the vehicle to verify the symptom.

3. Find the symptom in the chart below, and do the related procedures in the order listed until you find the cause.

•
•
•

Random misfire only
at low RPM and
under load

Check fuel pressure (see page 11-216).

Low compression.
Low quality fuel.
Correct EGR valve
function.

Random misfire only
during acceleration

Check fuel pressure (see page 11-216).

Malfunction in the
VTEC system (see
page 6-12).

Random misfire at
high RPM and load,
or under random
conditions

Check fuel pressure (see page 11-216).

Correct valve
clearance (see page
6-15).
