Mode II Self-Diagnostic Results
*11
Detected itemsCrank angle sensor circuit
Malfunction is detected when ...Either 1° or 180° signal is not entered for the first few seconds during engine cranking. Either 1° or 180° signal is not input often enough while the engine speed is higher than the specified rpm.
Check item (remedy)Harness and connector (If harness and connector are normal, replace crank angle sensor.)
12
Detected itemsAir flow meter circuit
Malfunction is detected when ...The air flow meter circuit is open or shorted. (An abnormally high or low voltage is entered.)
Check item (remedy)Harness and connector (If harness and connector are normal, replace air flow meter.)
13
Detected itemsEngine temperature sensor circuit
Malfunction is detected when ...The engine temperature sensor circuit is open or shorted. (An abnormally high or low output voltage is entered.)
Check item (remedy)Harness and connector. Engine temperature sensor
14
Detected itemsVehicle speed sensor circuit
Malfunction is detected when ...The vehicle speed sensor circuit is open or shorted.
Check item (remedy)Harness and connector. Vehicle speed sensor (reed switch)
*21
Detected itemsIgnition signal circuit
Malfunction is detected when ...The ignition signal in the primary circuit is not entered during engine cranking or running.
Check item (remedy)Harness and connector. Power transistor unit
43
Detected itemsThrottle sensor circuit
Malfunction is detected when ...The throttle sensor circuit is open or shorted. (An abnormally high or low voltage is entered.)
Check item (remedy)Harness and connector. Throttle sensor
NOTE
*: Check items causing a malfunction of crank angle sensor circuit first, if both code No. 11 and 21 come out at the same time.
HOW TO ERASE SELF-DIAGNOSTIC RESULTS
The malfunction code is erased from the backup memory on the E.C.U. when the diagnostic mode is changed from Mode II to Mode I. (Refer to "HOW TO SWITCH MODES".)
NOTE
When the battery terminal is disconnected, the malfunction code will be lost from the backup memory within 24 hours.
Before starting self-diagnosis, do not erase the stored memory before beginning self-diagnosis.
