TROUBLE DIAGNOSIS
Monitored item [Unit]
Description Remarks
ENG SPEED
[rpm] • Indicates the engine speed computed from the signals of the
crankshaft position sensor (POS) and camshaft position sen-
sor (PHASE). • Accuracy becomes poor if engine speed
drops below the idle rpm.
• If the signal is interrupted while the engine is
running, an abnormal value may be indicat-
ed.
MAS A/F SE-B1
[V] • The signal voltage of the mass air flow sensor is displayed. • When the engine is stopped, a certain value
is indicated.
• When engine is running, specification range is indicated in "SPEC".
B/FUEL SCHDL
[ms] • “Base fuel schedule” indicates the fuel injection pulse width
programmed into ECM, prior to any learned on board correc-
tion. • When engine is running, specification range
is indicated in "SPEC".

[%] • The mean value of the air-fuel ratio feedback correction fac-
tor per cycle is indicated. • When the engine is stopped, a certain value
is indicated.
• This data also includes the data for the air/
fuel ratio learning control.
• When engine is running, specification range is indicated in "SPEC".
COOLAN TEMP/S
[ ° C] or [ °F] • The engine coolant temperature (determined by the signal
voltage of the engine coolant temperature sensor) is dis-
played. • When the engine coolant temperature sen-
sor is open or short-circuited, ECM enters
fail-safe mode. The engine coolant temper-
ature determined by the ECM is displayed.

DTC P0116 ECT SENSOR
Component DescriptionINFOID:0000000006341821
The engine coolant temperature sensor is used to detect the engine
coolant temperature. The sensor
modifies a voltage signal from the
ECM. The modified signal returns to the ECM as the engine coolant
temperature input. The sensor uses a thermistor which is sensitive to
the change in temperature. The electrical resistance of the ther-
mistor decreases as temperature increases.

*: This data is reference value and is measured between ECM terminal 38 (Engine
coolant temperature sensor) and ground.
CAUTION:
Do not use ECM ground terminals wh en measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground ot her than ECM terminals, such as the ground.
On Board Diagnosis LogicINFOID:0000000006341822
NOTE:
If DTC P0116 is displayed with P0117 or P0118, first perform the trouble diagnosis for DTC P0117,
P0118. Refer to EC-687, "
DTC Confirmation Procedure".
DTC Confirmation ProcedureINFOID:0000000006341823
NOTE:
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
TESTING CONDITION:
Before performing the following procedure, do not add fuel.
1. Start engine and warm it up to normal operating temperature.
2. Rev engine up to 2,000 rpm for more than10 minutes.
3. Move the vehicle to a cool place, then stop engine and turn ignition switch OFF.
4. Check resistance between “fuel level s ensor unit and fuel pump” terminals 4 and 5.
5. Soak the vehicle until the resistance between “fuel level sensor unit and fuel pump” terminals 4 and 5
becomes 0.5 kΩ higher than the value measured before soaking.
CAUTION:
Never turn ignition switch ON during soaking time.

On Board Diagnosis LogicINFOID:0000000006342102
If the cooling fan or another component in the cooli ng system malfunctions, engine coolant temperature will
rise. When the engine coolant temperature reaches an abnormally high temperature condition, a malfunction
is indicated.
This self-diagnosis has the on e trip detection logic.
CAUTION:
When a malfunction is in dicated, be sure to replace the coolant. Refer to MA-27, "
ENGINE COOLANT :
Changing Engine Coolant". Also, replace the engine oil. Refer to MA-32, "ENGINE OIL : Changing
Engine Oil".
1. Fill radiator with coolant up to specified level with a filling speed of 2 liters per minute. Be sure to
use coolant with the proper mixture ratio. Refer to MA-15, "
Anti-freeze Coolant Mixture Ratio".
2. After refilling coolant, run engine to ensure that no water-flow noise is emitted.
Overall Function CheckINFOID:0000000006342103

DTC P1217 ENGINE OVER TEMPERATURE
Never remove the radiator cap when the engine is
hot. Serious burns could be caused by high pres-
sure fluid escaping from the reser voir tank or the radiator.
Wrap a thick cloth around cap. Carefully remove the cap by turning it a quarter turn to allow built-up
pressure to escape. Then turn the cap all the way off.
