REPLACEMENT
1. REMOVE REAR WHEEL
2. INSPECT PAD LINING THICKNESS
Check the pad thickness through the caliper inspection hole
and replace pads if not within the specification.
Minimum thickness: 1.0 mm (0.039 in.)
3. REMOVE BRAKE CALIPER
(a) Remove the 2 mounting bolts.
(b) Remove the caliper and suspend it so the hose is not
stretched.
HINT:
Do not disconnect the flexible hose.
4. REMOVE 2 PADS AND 4 ANTI-SQUEAL SHIMS
5. REMOVE 4 PAD SUPPORT PLATES
NOTICE:
The pad support plates can be used again provided that
they have sufficient rebound, no deformation, cracks or
wear, and have had all rust, dirt and foreign particles
cleaned off.
6. CHECK DISC THICKNESS AND RUNOUT
(See page BR-30)
7. INSTALL PAD SUPPORT PLATES
8. INSTALL NEW PADS
NOTICE:
When replacing worn pads, the anti-squeal shims must be
replaced together with the pads.
Install the 4 anti-squeal shims to the pads.
HINT:
Apply disc brake grease to both sides of the inner anti-squeal
shims (See page BR-24).
NOTICE:
Do not allow oil or grease to get on the rubbing face.
9. INSTALL CALIPER
(a) Draw out a small amount of brake fluid from the reservoir.
(b) Press in the pistons with a hammer handle or an equiva-
lent.
HINT:

Always change the pads on one wheel at a time as there
is a possibility of the opposite piston flying out.

If the piston is difficult to push in, loosen the bleeder plug
and push in the piston while letting some fluid escape.

CIRCUIT INSPECTION
DTC
C0200 / 31 - C1239 / 39Speed Sensor Circuit
CIRCUIT DESCRIPTION
The speed sensor detects wheel speed and sends the ap-
propriate signals to the ECU. These signals are used for control
of the ABS & BA & TRAC & VSC control system. The front and
rear rotors each have 48 serrations.
When the rotors rotate, the magnetic field emitted by the perma-
nent magnet in the speed sensor generates AC voltage. Since
the frequency of this AC voltage changes in direct proportion to
the speed of the rotor, the frequency is used by the ECU to de-
tect the speed of each wheel.

are not input for 15 sec.
2. Momentary interruption of the speed sensor signal oc-
curs at least 7 times in the time between switching the
ignition switch ON and switching it OFF.
3. Continuous noise occurs into the speed sensor signals
with a vehicle speed at 12 mph (20 km/h) or more.
4. The condition that the speed sensor signal circuit is
open continues for 0.12 sec. or more.

between the highest rotating and the second highest rotat-
ing wheels is within 1 mph (2 km/h), the slowest wheel ro-
tates at 0 mph (0 km/h), and the second slowest wheel
rotates at 7 mph (12 km/h) for 1 second or more.

INSPECTION PROCEDURE
1 Check shift solenoid valve SR operation.
PREPARATION:
(a) Jack up the vehicle.
(b) Remove the oil pan.
(c) Remove the shift solenoid valve SR.
CHECK:
Measure the resistance between the solenoid connector termi-
nal and the body ground.
OK:
Resistance: 11 to 15 W at 20°C (68°F)
CHECK:
Connect the battery positive lead to the solenoid connector ter-
minal and the battery negative lead to the solenoid body
ground.
OK:
Solenoid sounds operation noise.
NG Replace shift solenoid valve SR (See page
AT-8).

(1) Remove the spark plug that may be faulty from the
ignition coil assembly.
(2) Install the spark plug to the ignition coil assembly.
(b) Disconnect the injector connector.
(c) Ground the spark plug.
CHECK:
Check if spark occurs while the engine is being cranked.
CAUTION:
Always disconnect each injector connector.

DTC P0340 Camshaft Position Sensor ºAº Circuit
(Bank 1 or Single Sensor)
DTC P0341 Camshaft Position Sensor ºAº Circuit
Range/Performance (Single Sensor)
CIRCUIT DESCRIPTION
The camshaft position sensor (G signal) consists of a magnet iron core and pickup coil.
The G signal plate has 1 tooth on its outer circumference and is installed on the LH camshaft timing pulley.
When the camshafts rotate, protrusion on the signal plate and air gap on the pickup coil change, causing
fluctuations in the magnetic field and generating a voltage in the pickup coil.
The NE signal plate has 34 teeth and is mounted on the crankshaft. The NE signal sensor generates 34
signals at every engine revolution. The ECM detects the crankshaft angle and the engine revolution based
on the NE signals, and the cylinder and the angle of the G2 based on the combination of the G and NE sig-
nals.
DTC No.DTC Detection ConditionTrouble Area

P0341
While crankshaft rotates twice, camshaft position sensor
signal will be input to ECM 12 times or more (1 trip detec-
tion logic)

Hint:
Under normal condition, the camshaft position signal is
input into the ECM 3 times per 2 engine revolutions
