Engine General Information and Diagnosis: 1A-11
NOTE
• If two or more items fail at once, the self-diagnostic indication appears according to the priority
order. The indication repeats three times.
• If the failed item remains, the self-diagnostic indication appears again after turning the ignition
switch “ON”.
• After correcting the failed item, the self-diagnostic indication appears until the ECM receives the
proper signal with the engine running.
• Cancellation of the self-diagnostic indication is automatically performed when the failure is
corrected and a normal signal is received by the ECM for a period of 20 – 30 seconds.
• The Rectifier/Regulator self-diagnostic indication may not be displayed when the ignition switch is
turned “ON” because the ECM cannot detect rectifier/regulator charging output if the engine is not
running.
Under this condition, the buzzer will not sound a 1 – 1 code.
However, if the rectifier/regulator has failed, the self diagnostic indication will appear again after
starting the engine.

Failed Item Condition
MAP sensor 1
• No signal (With engine running).
• Receiving an out of range “38 – 855 mmHg (1.49 – 33.66 inHg) (0.2 – 4.5
V)” signal (With the engine running.).
Cylinder temp. sensor
• No signal.
• Receiving an out of range “– 46 to + 170 °C (– 114.8 – +338 °F) (0.10 – 4.6
V)” signal.
IAT sensor
• No signal.
• Receiving an out of range “– 46 to + 169 °C (– 114.8 – +336.2 °F) (0.10 –
4.6 V)” signal.
CKP sensor
• During one crankshaft rotation, 32 signals are not received by the ECM.
• During cranking, CMP sensor signal is received by the ECM, but not CKP
sensor signal.
CMP sensor
• During three crankshaft rotations, the normal CMP sensor signal pattern is
not received by the ECM.
Air intake system
• The engine operates at an abnormally high speed when the ECM is
receiving a completely closed signal from the throttle position sensor.
(Criteria: 2 100 r/min minimum)
MAP sensor 2
• From TPS sensor, the full close signal is inputted, but from the MAP
sensor, the signal voltage exceeds 2.4 V.
Exhaust manifold temp. sensor
• No signal.
• Receiving an out of range “– 46 to + 170 °C (– 114.8 – +338 °F) (0.10 – 4.6
V)” signal.
Fuel injector • No operation signal from the ECM.
Throttle position sensor
• No signal.
• Receiving an out of range “0.2 – 4.8 V” signal.
Shift position sensor
• No signal.
• Receiving an out of range “0.2 – 4.8 V” signal.
