CIRCUIT DESCRIPTION
The flat type knock sensor (non–resonant type) has a structure that can detect vibration in a wider band of
frequency, from about 6 kHz to 15 kHz and has the following features:
The knock sensor is fitted on the cylinder block to detect engine knocking.
The sensor contains a piezoelectric element which generates voltage when it becomes deformed. This
occurs when the cylinder block vibrates due to knocking. If engine knocking occurs, the ignition timing
is retarded to suppress it.

HINT:
If the ECM detects DTC P0325, P0327 and/or P0328, it enters fail–safe mode in which the corrective re-
tarded angle value is set to the maximum value.

HYDRAULIC TEST
1. PERFORM HYDRAULIC TEST
(a) Measure the line pressure.
NOTICE:

Perform the test at the normal operating ATF (Automatic Transmission Fluid) temperature 50
to 80
C (122 to 176
F).

The line pressure test should always be carried out in pairs. One technician should observe
the conditions of wheels or wheel stopper outside the vehicle while the other is doing the test.

Be careful to prevent SST’s hose from interfering with the exhaust pipe.

This check must be conducted after checking and adjusting engine.

Perform under condition that A/C is OFF.

When conducting stall test, do not continue more than 10 seconds.
(1) Warm up the ATF.
(2) Remove the test plug on the left side of the trans-
axle case and connect SST.
SST 09992–00095 (09992– 00231, 09992–00271)
(3) Fully apply the parking brake and chock the 4
wheels.
(4) Connect an Intelligent Tester II to the DLC3.
(5) Start the engine and check idling speed.
(6) Keep your left foot pressing firmly on the brake ped-
al and shift into D position.
(7) Measure the line pressure when the engine is idling.
(8) Depress the accelerator pedal all the way down.
Quickly read the highest line pressure when engine
speed reaches stall speed.
(9) In the same way, do the test in R position.
Specified line pressure:
ConditionD position kPa (kgf / cm2, psi)R position kPa (kgf / cm2, psi)
Idling372 to 412 kPa
(3.8 to 4.2 kgf/cm2, 54 to 60 psi)
553 to 623 kPa
(5.6 to 6.4 kgf/cm2, 80 to 90 psi)
Stall test1,126 to 1,226 kPa
(11.5 to 12.5 kgf/cm2, 163 to 178 psi)
1,664 to 1,864 kPa
(17.0 to 19.0 kgf/cm2, 241 to 270 psi)
Evaluation:
ProblemPossible cause
If the measured values at all positions are higher
Shift solenoid valve SLT defective

Regulator valve detective
If the measured values at all positions are lower

Shift solenoid valve SLT defective

Regulator valve detective

Oil pump defective
If pressure is low in the D position only
D position circuit fluid leak

Forward clutch defective
If pressure is low in the R position only

R position circuit fluid leak

Reverse clutch defective

(c) Check the indicator.
(1) Turn the ignition switch to the ON position.
(2) Check that the CRUISE main indicator light comeson when the cruise control main switch ON–OFF
button is pushed on, and that the indicator light
goes off when the ON–OFF button is pushed off.
HINT:
If there is a problem with the indicator light, inspect the CRUISE
main indicator light circuit ( see page 05–327).
HINT:
If a malfunction occurs in the vehicle speed sensors, stop lamp
switch assy or other related parts during cruise control driving,
the ECM actuates AUTO CANCEL of the cruise control. Then
the CRUISE main indicator light starts to blink, informing the
driver of the malfunction. At the same time, data of the malfunc-
tion is stored as a diagnostic trouble code (DTC).
