• In the DTC check, it is very important to determine
whether the problem indicated by the DTC either: 1)
still occurs, or 2) occurred in the past but has returned
to normal. In addition, the DTC should be compared
to the problem symptom to see if they are related. For
this reason, DTCs should be checked before and after
confirmation of symptoms (i.e., whether or not
problem symptoms exist) to determine current system
conditions, as shown in the flowchart below.
• Never skip the DTC check. Failing to check DTCs
may, depending on the case, result in unnecessary
troubleshooting for systems operating normally or
lead to repairs not related to the problem. Follow the
procedures listed in the flowchart in the correct order.

ES–1062GR-FE ENGINE CONTROL SYSTEM – SFI SYSTEM
ES
DESCRIPTION
Refer to DTC P0335 (See page ES-220).
MONITOR DESCRIPTION
DTC P0016 and P0018
The ECM optimizes the valve timing by using the VVT (Variable Valve Timing) system to control the intake
camshaft. The VVT system includes the ECM, the Oil Control Valve (OCV) and the VVT controller.
The ECM sends a target duty-cycle control signal to the OCV. This control signal regulates the oil
pressure applied to the VVT controller. The VVT controller can advance or retard the intake camshaft. The
ECM calibrates the intake valve timing by setting the intake camshaft to the most retarded angle while the
engine is idling. The ECM closes the OCV to retard the cam. The ECM stores this value as the VVT
learning value. When the difference between the target and actual intake valve timings is 5
CA
(Crankshaft Angle) or less, the ECM stores it.
If the VVT learning value matches the following conditions, the ECM determines the existence of a
malfunction in the VVT system, and sets the DTC.
• The VVT learning value: Less than 18.5
CA, or more than 43.5 CA.
• The above condition continues for 18 seconds or more.
This DTC indicates that the intake camshaft has been installed toward the crankshaft at an incorrect
angle, caused by factors such as the timing chain having jumped a tooth.
This monitor begins to run after the engine has idled for 5 minutes.
DTC P0017 and P0019
The ECM checks valve timing (VVT learning value) on the exhaust side while the engine is running at a
low speed, in order to monitor the gap between current and target valve timings on the exhaust side. The
VVT learning value is calculated from the positions of the camshaft and crankshaft. The camshaft will
come to the most retarded position when the engine is running at a low speed. If the camshaft position is
normal, the VVT learning value should be within the specified range. If the VVT learning value is not within
the specified range, the ECM determines this as a malfunction.

INSPECTION
1. INSPECT FRONT DIFFERENTIAL
(a) Using a dial indicator, measure the backlash of one
pinion gear while holding the front differential side
gear toward the case.
Standard backlash:
0.05 - 0.20 mm (0.0020 - 0.0079 in.)
NOTICE:
Do not mount the surface of front differential
case which contacts with bushing in a vise.
If the backlash is not within the specified value, refer
to the table below and select a thrust washer which
will ensure that the backlash is within the specified
value.
Thrust washer thickness: mm (in.)
(b) Engage the front differential side to the above
mentioned front differential case.
(c) Install the differential case LH to the front differential
case and measure its center.
(d) After that, remove the differential case LH.
(e) Using a straight edge and feeler gauge, measure
the clearance between the front differential case
and the front differential side gear.
HINT:
• t= Thrust washer thickness
• L= Clearance
• t= L-0.162 - 0.265 mm (0.0064 - 0.0104 in.)
If the clearance is not within the specified value,
refer to the table below and select a thrust washer
which will ensure that the clearance is within the
specified value.
Thrust washer thickness: mm (in.)

If the clearance is not within the specified value,
parts may have been assembled incorrectly, so
check and reassemble it.
2. INSPECT CENTER DIFFERENTIAL
(a) Pressing and holding the differential spider toward
the differential case RH, measure the pinion's
backlash with a dial indicator as illustrated.
Standard backlash:
0.05 - 0.20 mm (0.0020 - 0.0079 in.)
If the backlash is not within the specified value, refer
to the table below and select a thrust washer which
will ensure that the backlash is within the specified
value.
Thrust washer thickness: mm (in.)
(b) Temporarily install the differential side gear thrust
washer No.2 LH, center differential side gear conical
spring washer and differential case No.2 to the
differential case LH.
HINT:
Ensure that the conical washers is installed
correctly.
(c) Install the differential intermediate case to the above
and fix them with 4 bolts.
