DTC P0234 TC SYSTEM

DTC P0234 TC SYSTEMPFP:14411
DescriptionEBS0120N
The load from the turbocharger boost control solenoid valve controls
the actuator. By changing the variable nozzle vane opening through
the rods, the intake air volume is adjusted.
The turbocharger boost control solenoid valve is moved by ON/OFF
pulse from the ECM. The longer the ON pulse, the charge air pres-
sure rises.
On Board Diagnosis LogicEBS0120P
The MI will not light up for these self-diagnoses.
NOTE:

If DTC P0234 is displayed with DTC P0652 or P0653, first perform trouble diagnosis for DTC P0652
or P0653. Refer to EC-1579, "
DTC P0652, P0653 SENSOR POWER SUPPLY" .
Overall Function CheckEBS0120Q
Use this procedure to check the overall function of the turbocharger. During this check, a DTC might not be
confirmed.
1. Start engine and let it idle.
2. Make sure that turbocharger control actuator rod moves slightly
when engine is started.
3. If NG, go to EC-1502, "
Diagnostic Procedure" .

6. Check A/T fluid condition.

If A/T fluid is very dark or smells burned, checking operation
of A/T. Flush cooling system after repair of A/T.

If A/T fluid contains frictional material (clutches, bands, etc.),
replace radiator and flush cooler line using cleaning solvent
and compressed air after repair of A/T. Refer to CO-12,
"RADIATOR" , CO-15, "RADIATOR (ALUMINUM TYPE)" .
7. Install the removed A/T fluid level gauge in the A/T fluid charging
pipe.
CAUTION:
Firmly fix the A/T fluid level gauge to the A/T fluid charging
pipe using a stopper attached.
Changing A/T FluidECS004Q8
1. Warm up A/T fluid.
2. Stop engine.
3. Drain A/T fluid from drain plug and refill with new A/T fluid. Always refill same volume with drained fluid.
Refer to MA-17, "
RECOMMENDED FLUIDS AND LUBRICANTS" .
CAUTION:
Do not reuse drain plug gasket.
4. Run engine at idle speed for five minutes.
5. Check A/T fluid level and condition. Refer to AT- 1 6 , "
Checking
A/T Fluid" . If A/T fluid is still dirty, repeat steps 2 through 5.

d. Remove A/T fluid level gauge and wipe clean lint-free paper.
CAUTION:
When wiping away the A/T fluid level gauge, always use lint-free paper, not cloth one.
e. Re-insert A/T fluid level gauge into charging pipe as far as it will go.
CAUTION:
To check fluid level, insert the A/T fluid level gauge until the cap contacts the end of the A/T fluid
charging pipe, with the A/T fluid level gauge reversed from the normal attachment conditions.
f. Remove A/T fluid level gauge and note reading. If reading is at low side of range, add fluid to the A/T fluid
charging pipe.
CAUTION:
Do not overfill.
4. Drive vehicle for approximately 5 minutes in urban areas.
5. Re-check fluid level at fluid temperatures of 50 to 80°C (122 to 176°F) using “HOT” range on A/T fluid
level gauge.
CAUTION:

When wiping away the A/T fluid level gauge, always use lint-free paper, not cloth one.

To check fluid level, insert the A/T fluid level gauge until the cap contacts the end of the A/T fluid
charging pipe, with the A/T fluid level gauge reversed from the normal attachment conditions.
6. Check fluid condition.

If fluid is very dark or smells burned, refer to AT section for
checking operation of A/T. Flush cooling system after repair of
A/T.

If A/T fluid contains frictional material (clutches, bands, etc.),
replace radiator and flush cooler line using cleaning solvent
and compressed air after repair of A/T. Refer to CO-12,
"RADIATOR" , CO-15, "RADIATOR (ALUMINUM TYPE)" .

pipe.
Changing A/T FluidELS000BW
1. Warm up A/T fluid.
2. Stop engine.

Always refill same volume with drained fluid.
4. Run engine at idle speed for five minutes.
5. Check fluid level and condition. Refer to MA-40, "
Checking A/T Fluid" . If fluid is still dirty, repeat steps 2
through 5.
Checking Transfer OilELS000BT
Check for oil leakage and oil level.
