Engine Performance – Judges Answer Key

1

The vehicle needs to be driven or an equivalent statement. Explanation: A specific drive cycle and/or a combination of drive cycles is needed. The permanent code will erase itself if the repair is confirmed and the original problem that set the code is corrected.

5

2

Source voltage, B+ or 12 volts etc.

5

3

Six (three signals per two crankshaft revolutions) Explanation: Vehicles with variable valve timing need more than one signal per camshaft revolution. This is shown in the scope pattern of the cam sensor in the terminals of the ECM reference.

5

4

Turning the steering wheel

5

5

Since there is high resistance in the fuel pump circuit the fuel pump may not attain the proper pressure causing the FUEL TRIM to be POSITIVE

6

Mass Sir Flow Meter (the intake air temperature sensor is built into the MAF). The student must figure this out by the wiring diagram. Intake air Temperature sensor is NOT acceptable

5

7

AC or Alternating Current

5

8

The brake booster or the brake booster vacuum hose/source or a broken break booster check valve, etc. Explanation: There is a large vacuum leak indicated by the 203 Short Term Fuel Trim. Since the brake pedal is hard (it uses engine vacuum for power assisted brakes) the obvious next step is to inspect the condition of the brake booster vacuum hose.

5

9

A bad fuel injector a bad ignition coil Explanation: P0303 is a cylinder misfire code for cylinder #3. Only these 2 parts on the list will cause a misfire of only one cylinder.

Use the Electrical Wiring Diagram and the Terminals of the ECM reference as needed to answer the questions. For questions 10 to 16 FOUR components labeled “A” through “D” are available for you at a nearby table (do not touch these items). For all DVOM readings (except when directed otherwise) the dial is on DC VOLTS, the BLACK LEAD is grounded, and the RED LEAD is at the point mentioned.

1. After replacing a coolant temperature sensor you notice that the scanner information indicates that a permanent DTC is recorded. When the engine is running the Check Engine light is off. What would be your next move and why?


2. With the Key on, Engine off, and the fuel injector connected, what should be the voltage reading at the YELLOW wire at the number THREE fuel injector?


3. If the crankshaft rotates 4 complete revolutions, how many Cam Shaft Position Sensor signals does the ECM receive?


Station #4(page 2)


4. Terminal 53 on the ECM Connector”C24” normally toggles from 0 volts to 5 volts. What condition (driver action) causes the voltage to go to 5 volts?


5. With the vehicle running, .3 volts is recorded at terminal 5 of the Fuel Pump connector. How might this effect Fuel Trim?


6. Based on the scanner data below (figure #1) and the information provided what part needs replacing? In figures #2 & 3 the data is recorded after the sensor is disconnected.

7. What type of current (AC or DC) would you find what terminals 121 and 122 of ECM connector C24 while the vehicle is running?


8. The customer states that the Check Engine light is on and that the brake pedal is very hard to push. You note that a DTC PO171 (system too lean bank 1), you clear the code, and it does not immediately come back. Based on the scanner data below and the customer’s concern, what would you inspect or suspect as the problem?

9. Which two parts might set a DTC P0303? A bad VSV purge solenoid, a bad fuel injector, an open Air Fuel Ratio, a bad ignition coil, or a bad camshaft timing control valve.


10. Use the electrical wiring diagram as a reference for this question. Component “A” is designated B1S2. A DTC P0037 HO2S Heater Control Circuit Low (Bank 1 Sensor 2) was set. Using an ohmmeter the resistance of wires (terminals 1 & 2) of Component “A” and get an “OL” reading? What do you need to do to repair the vehicle.

11. Component “A” is designated B1S2. Where is it located on the vehicle?


12. If the TOP “O” ring is split on component “B” what will leak?


13. If the BOTTOM “O” component “B” ring is split what will leak?


14. Component “C” is part of the _____________ emission system of the Vehicle?


15. If component “D” is stuck closed what harmful exhaust emission will increase?


16. If component “D” is stuck open what will be the biggest complaint?


17. What FIVE gasses does a 5 gas emission analyzer measure?


1. Oxygen
