ON-BOARD DIAGNOSTIC [ENGINE CONTROL SYSTEM (FS)]

01–02B–19

01–02B

DTC P0031 [FS]

A3U010201084W01

Diagnostic procedure

DTC P0031

HO2S heater (front) circuit low

DETECTION 

CONDITION

•

PCM monitors HO2S heater (front) control signal at PCM terminal 94. If PCM turns the HO2S heater (front) 
off but voltage at terminal 94 still remains low, PCM determines that HO2S heater (front) circuit has 
malfunction.

Note

•

HO2S heater (front) is controlled by a duty signal.

Diagnostic support note

•

This is an intermittent monitor (O

2

 sensor heater).

•

MIL illuminates if PCM detects the above malfunction condition in two consecutive drive cycles.

•

PENDING CODE is available if PCM detects the above malfunction condition during first drive cycle.

•

FREEZE FRAME DATA is available.

•

DTC is stored in PCM memory.

POSSIBLE 

CAUSE

•

HO2S (front) malfunction

•

Open circuit between ignition switch terminal C and HO2S (front) terminal C

•

Open circuit between HO2S (front) terminal D and PCM terminal 94

•

Short to ground circuit between HO2S (front) terminal D and PCM terminal 94

•

Poor connection at HO2S (front) or PCM connector

•

PCM malfunction

STEP

INSPECTION

ACTION

1

VERIFY FREEZE FRAME DATA HAS BEEN 
RECORDED

•

Has FREEZE FRAME DATA been recorded?

Yes Go to next step.

No

Record FREEZE FRAME DATA on repair order, then go to 
next step.

2

VERIFY RELATED REPAIR INFORMATION 
AVAILABILITY

•

Check for related Service Bulletins availability.

•

Is any related repair information available?

Yes Perform repair or diagnosis according to available repair 

information.

•

If vehicle is not repaired, go to next step.

No

Go to next step.

3

INSPECT HO2S (FRONT) CONNECTOR FOR 
POOR CONNECTION 

•

Turn ignition key to OFF.

•

Disconnect HO2S (front) connector.

•

Check for poor connection (damaged/pulled-
out pins, corrosion, etc.).

•

Is there malfunction?

Yes Repair or replace terminal, then go to Step 9.

No

Go to next step.
