1.CHECK TURBOCHARGER BOOST SENSOR-I
1. Turn ignition switch OFF.
2. Remove turbocharger boost sensor with its harness connected.
3. Turn ignition switch ON.
4. Select “DATA MONITOR” mode with CONSULT-III.
5. Check “BOOST PRESS” and “ATOMOS PRESS” indication.
If the value is not very close to
“ATOMOS PRESS”, maximum pressure difference between “ATOMOS
PRESS” and “BOOST PRESS” with the ignition switch ON (engine stop) = ± 50 mbar?
YES >> GO TO 2.
NO >> Replace turbocharger boost sensor.
2.CHECK TURBOCHARGER BOOST SENSOR-II
1. Use pump to apply turbocharger boost sensor as shown in the
figure.
2. Apply a pressure of between 10 kPa(0.100 bar, 0.102 kg/cm
2,
1.5 psi) - 13 kPa(0.130 bar, 0.133 kg/cm
2, 1.9 psi) [maximum
pressure to be applied: 13 kPa(0.130 bar, 0.133 kg/cm
2, 1.9
psi)].
3. Select “DATA MONITOR” mode with CONSULT-III.
4. Check “BOOST PRESS” indication with that given by the vac-
uum pump.
If there is no discrepancy?
YES >> INSPECTION END
NO >> Replace turbocharger boost sensor.

DTC DETECTION LOGIC
NOTE:
Conditions for applying the diagnostic procedure to the stored DTCs:
The DTC becomes present during the first 30 seconds after the engine starts.
 In low ambient temperature conditions, diagnostic can.t make difference between a normal long engine start
and abnormal long engine start. So, DTC must be take in account only if customer complains about too long
or impossible engine start not only in cold conditions but also and especially in warm conditions. If customer
complains only in cold conditions, root cause of the problem could elsewhere like low battery level, bad fuel
specification (too viscous fuel). This DTC could appear after fuel filter too.
Special notes:
Starting and engine operation difficult or impossible.
