*11
Detected itemsCrank angle sensor circuit
Malfunction is detected when ...Either 1deg. or 180deg. signal is not entered for the first few seconds during engine cranking. Either 1deg. or 180deg. 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
*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.
