No. TROUBLESHOOTING ITEM DESCRIPTION
1 Melting of main or other fuses—
2 MIL illuminates MIL is illuminated incorrectly.
3 Will not crank Starter does not work.
4Hard to start/long crank/erratic start/erratic
crankStarter cranks engine at normal speed but engine requires excessive
cranking time before starting.
5 Engine stalls. After start/at idle Engine stops unexpectedly at idle and/or after start.
6 Cranks normally but will not start Starter cranks engine at normal speed but engine will not run.
7 Slow return to idle Engine takes more time than normal to return to idle speed.
8 Engine runs rough/rolling idleEngine speed fluctuates between specified idle speed and lower
speed and engine shakes excessively.
9 Fast idle/runs onEngine speed continues at fast idle after warm-up.
Engine runs after ignition switch is turned to off.
10 Low idle/stalls during decelerationEngine stops unexpectedly at beginning of deceleration or recovery
from deceleration.
11Engine stalls/quits. Acceleration/cruiseEngine stops unexpectedly at beginning of acceleration or during
acceleration.
Engine stops unexpectedly while cruising.
Engine runs rough. Acceleration/cruise Engine speed fluctuates during acceleration or cruising.
Misses Acceleration/cruise Engine misses during acceleration or cruising.
Buck/jerkAcceleration/cruise/
decelerationVehicle bucks/jerks during acceleration, cruising, or deceleration.
Hesitation/stumble Acceleration Momentary pause at beginning of acceleration or during acceleration
Surges Acceleration/cruise Momentary minor irregularity in engine output
12 Lack/loss of power Acceleration/cruisePerformance is poor under load.
(e.g., power down when climbing hills)
13 Knocking/pinging Acceleration/cruiseSound is produced when air/fuel mixture is ignited by something other
than spark plug. (e.g., hot spot in combustion chamber)
14 Poor fuel economy Fuel economy is unsatisfactory.
15 Emission compliance Fails emissions test.
16 High oil consumption/leakage Oil consumption is excessive.
17Cooling system
concernsOverheating Engine runs at higher than normal temperature/overheats.
18Cooling system
concernsRuns cold Engine does not reach normal operating temperature.
19 Exhaust smoke Blue, black, or white smoke from exhaust system
20 Fuel odor (in engine compartment) Gasoline fuel smell or visible leakage
21 Engine noise Engine noise from under hood
22 Vibration concerns (engine) Vibration from under hood or driveline
23 A/C does not work sufficiently.A/C compressor magnetic clutch does not engage when A/C is turned
on.
24A/C is always on or A/C compressor runs
continuously.A/C compressor magnetic clutch does not disengage.
25 A/C is not cut off under WOT conditions. A/C compressor magnetic clutch does not disengage under WOT.
26 Exhaust sulphur smell Rotten egg smell (sulphur) from exhaust
27 Constant voltage Incorrect constant voltage
