PGM-FI Self-diagnosis malfunction indicator lamp (MIL) failure codes
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.
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 Faulty ECM Engine does not start
No blinks Faulty ECM (PGM-FI warning indicator output) Engine operates normally
Stay lit Short circuit in service check connector
Faulty ECM (PGM-FI warning indicator output)
Engine operates normally
1 Blink Open or short circuit in MAP sensor line (in the ECM)
Faulty MAP sensor
Poor idle
7 Blinks Loose or poor contact on ECT sensor
Open or short circuit in ECT sensor wire
Faulty ECT sensor
Hard starting at a low temperature
(Simulate using numerical values; 90 ˚C/194˚F)

8 Blinks Open or short circuit in TP sensor line (in the ECM)

(Simulate using numerical values; throttle open 0˚)
9 Blinks Open or short circuit in IAT sensor line (in the ECM) Engine operates normally
(Simulate using numerical values; 25˚C/77˚F)
12 Blinks Loose or poor contact on injector connector
Open or short circuit in injector wire
