PGM-FI Self-diagnosis Malfunction Indicator Lamp (MIL) failure codes
y The PGM-FI MIL denotes the failure codes (the number of blinks from 0 to 54). When the indicator lights for 1.3 seconds, it is equivalent to ten blinks. For example; a 1.3 second
illumination and two blinks (0.5 second x 2) of the indicator equals 12 blinks. Follow code 12 troubleshooting.
y When more than one failure occurs, the MIL shows the blinks in the order of lowest number to highest number. For example; if the indicator blinks once, then seven times, two
failures have occurred. Follow codes 1 and 7 troubleshooting.
Number of blinks Causes Symptoms
0 No blinks y Faulty ECM y Engine does not start
No blinks y Faulty ECM (PGM-FI warning indicator output) y Engine operates normally
Stays lit y Short circuit in service check connector
y Faulty ECM (PGM-FI warning indicator output)
y Engine operates normally
1 Blink y Open or short circuit in MAP sensor line (in the ECM)
y Faulty MAP sensor
y Poor idle
7 Blinks y Loose or poor contact on ECT sensor
y Open or short circuit in ECT sensor wire
y Faulty ECT sensor
y Hard starting at a low temperature
(Simulate using numerical values; 90 ÝC/194 ÝF)
y Cooling fan does not stop
8 Blinks y Open or short circuit in TP sensor line (in the ECM)

y Poor engine response when operating the throttle quickly
(Simulate using numerical values; throttle open 0Ý)
9 Blinks y Open or short circuit in IAT sensor line (in the ECM) y Engine operates normally
(Simulate using numerical values; 25ÝC/77 ÝF)
12 Blinks y Loose or poor contact on injector connector
y Open or short circuit in injector wire
y Faulty injector
y Engine does not start
54 Blinks y Loose or poor contact on bank angle sensor connector
