DTC DETECTION LOGIC
| DTC | Trouble diagnosis name | DTC detection condition | Possible causes |
| P1588 | G Sensor Circuit Range/Performance | When the following diagnosis conditions are
satisfied and the detection conditions are satisfied
twice in the same DC: - Diagnosis condition (1 second or more) - The rate of change in G sensor detection value (mV): Between −15 and +15 inclusive - Detection condition - The rate of change in acceleration/deceleration stays +0.0273 G or more/−0.0273 or less at least for 5 seconds or more. |
G sensor |
NOTE: DC stands for "DRIVING CYCLE" and indicates a series of driving cycle of "Ignition switch OFF → ON → driving → OFF".
DTC CONFIRMATION PROCEDURE
CAUTION: Be careful of the driving speed.
1.PREPARATION BEFORE WORK
If another "DTC CONFIRMATION PROCEDURE" occurs just before, turn ignition switch OFF and wait for at least 10 seconds, then perform the next test.
>> GO TO 2.
2.CHECK DTC DETECTION
With CONSULT
CAUTION: Never stop the engine.
Selector lever : "D" position
G SPEED : 0.05 G or more
Is "P1588" detected?
YES >> Go to TM "Diagnosis Procedure".
NO >> INSPECTION END
1.CHECK G SENSOR SIGNAL
With CONSULT

Is the inspection result normal?
YES >> GO TO 2.
NO >> GO TO 3.
2.G SENSOR CALIBRATION (PART 1)
With CONSULT
>> Perform "G SENSOR CALIBRATION". Refer to TM "Work Procedure".
3.CHECK G SENSOR
: Direction of gravitational
force


Is the inspection result normal?
YES >> GO TO 4.
NO >> Replace G sensor.TM "Removal and Installation".
4.G SENSOR CALIBRATION (PART 2)
With CONSULT
>> Perform "G SENSOR CALIBRATION". Refer to TM "Work Procedure".
IDLE SPEED
Inspection
1.CHECK IDLE SPEED
With CONSULT
Check idle speed in "DATA MONITOR" mode with CONSULT.
Without CONSULT
Check idle speed by installing the pulse type tachometer clamp on the loop
wire or on suitable high-tension
wire which installed between No.1 ignition coil and No.1 spark plug.

Positive crankcase ventilation
Inspection
1.CHECK PCV VALVE
With engine running at idle, remove PCV valve from rocker cover. A
properly working valve makes a hissing noise as air passes through
it. A strong vacuum should be felt immediately when a finger is
placed over valve inlet.
Is the inspection result normal?
YES &g ...
