[. . . ] If the MIL stays illuminated, it warns the customer a fault is currently happening, and dealer service is required. Upon receipt, the dealer technician can access the fault code(s) to help determine what portion of the system is malfunctioning. The codes are accessed through the key switch and displayed as blinks or flashes of the MIL. Turn the key switch to the ON and OFF, then ON and OFF, then ON, leaving it on in the third sequence. The time between sequences must be less than 2. 5 seconds. 5. 27 Section 5 EFI Fuel System Example of Diagnostic Display (0) One second pause (1) One second pause (0) One second pause Fault Code 0107 (7) Three second pause (6) One second pause (1) Figure 5-29. End Code 61 This is a 0107 fault code with the 61 message end code. After the problem has been corrected, the fault codes may be cleared by following the ECU Reset and TPS Learn Procedures. The chart on the following page lists the fault codes, and what they correspond to. Following the chart is a list of the individual codes with an explanation of what triggers them, what symptoms might be expected, and the probable causes. If the equipment manufacturer has not added a MIL to the equipment, one can be added easily for quick diagnostics. The main engine to vehicle connection will have a tan wire which is the ground for the MIL. Either incandescent or LED type bulbs can be used for the MIL as long as they do not draw more than 0. 1 amps. Exhaust system leak (muffler, flange, oxygen sensor mounting boss, etc. ). Fuel in the crankcase oil. Condition: Shorted connection or faulty sensor. Difference in voltage between sensed voltage and actual sensor voltage. Code: Component: Fault: 0171 Fuel System Condition: Too high pressure at high pressure fuel line, TPS malfunction, shorted connection, faulty sensor or fuel pump module failure. Difference in voltage between sensed voltage and actual sensor voltage. Fuel (fuel type/quality, injector, fuel pressure too high, fuel pump module or lift pump). Lift pump diaphragm is ruptured. Maximum adaptation limit exceeded Condition: Fuel inlet screen/filter plugged, low pressure at high pressure fuel line, TPS malfunction, shorted connection, faulty sensor, low fuel or wrong fuel type. Difference in voltage between sensed voltage and actual sensor voltage. ECU-to-harness connection problem. 5. 32 Section 5 EFI Fuel System Code: Component: Fault: 0174 Fuel System Lean fuel condition Code: Component: Fault: 0202 Fuel Injector Injector 2 Circuit Malfunction Condition: Fuel inlet screen/filter plugged, low pressure at high pressure fuel line, TPS malfunction, shorted connection or faulty sensor. Lean condition (check oxygen sensor signal with VOA and see Oxygen Sensor section). Poor system ground from ECU to engine, causing rich running while indicating lean. [. . . ] Attach the air cleaner base bracket to the cylinder heads with four hex flange screws behind any control panel or bracket. Attach the air cleaner base to the lower bracket with the two M5 screws through the lower section of the base. lb. ), and the two lower M5 mounting screws (when applicable) to 4. 0 N·m (35 in. Move the governor lever toward the throttle body as far as it will go (wide-open throttle) and hold in position. [. . . ]
