PRECAUTION
1. INITIALIZATION
NOTICE:
• Perform RESET MEMORY (AT initialization) when
replacing the automatic transaxle assembly, engine
assembly or ECM (See page AX-16).
• Perform REGISTRATION (VIN registration) when
replacing the ECM (See page ES-15).
HINT:
Initialization cannot be completed by only removing the
battery.
2. FOR USING INTELLIGENT TESTER
CAUTION:
Observe the following items for safety reasons:
• Before using the tester, read the instruction
manual.
• Prevent the tester cable from being caught on the
pedals, shift lever and steering wheel when
driving with the tester connected to the vehicle.
• When driving the vehicle for testing purposes
using the tester, two persons are required. One is
for driving the vehicle, and the other operates the
tester.
3. FOR USING BATTERY DURING INSPECTION
(a) While using the battery during inspection, do not
bring the positive and negative tester probes too
close to each other as a short circuit may occur.
4. COOLING FAN SYSTEM
NOTICE:
• When the ignition switch is turned off and the engine
temperature is high, the cooling fans may operate for
approximately 3 minutes.
• After turning the ignition switch off, keep hands and
objects away from the fans when they are operating.
HINT:
If all of the following are met for a certain period of time during
a few minute period immediately before the engine is
stopped, the electric fans will continue to operate for 3
minutes after the engine is stopped. This is performed to
ensure restartability and stabilize idle speed.
– The intelligent tester indicates a very high coolant
temperature.
– The intelligent tester indicates a high outside air
temperature.
– The vehicle has been driven under high load (driving on an
uphill or equivalent).
The following sensors are used for this control:
– Coolant temperature sensor
– Outside air temperature sensor
–MAF sensor
– Vehicle speed sensors

2GR-FE ENGINE CONTROL SYSTEM – SFI SYSTEMES–291
ES
DESCRIPTION
The speed sensor detects the wheel speed and sends the appropriate signals to the skid control ECU.
The skid control ECU converts these wheel speed signals into a 4-pulse signal and outputs it to the ECM
via the combination meter. The ECM determines the vehicle speed based on the frequency of these pulse
signals.
MONITOR DESCRIPTION
The ECM assumes that the vehicle is being driven when the transmission counter gear indicates more
than 300 rpm and over 30 seconds have passed since the park / neutral position switch was turned OFF.
If thre is no signal from the vehicle speed sensor with these conditions satisfied, the ECM concludes that
the vehicle speed sensor is malfunctioning. The ECM will turn on the MIL and a DTC will be set.
MONITOR STRATEGY
TYPICAL ENABLING CONDITIONS

DTC No. DTC Detection Condition Trouble Area
P0500The ECM detects the following conditions
simultaneously for 2 seconds (1 trip detection logic):
• No SPD (speed sensor) signal while ECM detects
NC (transmission counter gear) signal is more than
300 rpm
• Park / neutral position switch is OFF (When shift
lever is in other than P and N positions)• Open or short in speed sensor circuit
• Speed sensor

(a) Shift the transmission gear selector lever to the neutral
position.
(b) Jack up the vehicle.
(c) Turn the ignition switch to the ON position.
(d) Measure the voltage between the terminal of the
combination meter and body ground while the wheel is
turned slowly.
Standard voltage
HINT:
The output voltage should fluctuate up and down,
similarly to the diagram, when the wheel is turned slowly.
