ON-VEHICLE INSPECTION
HINT:
In this section, the terms Cold and Hot refer to the temperature of the coils. Cold means approximately -10 to 50 ° C (14 to 122 ° F). Hot means approximately 50 to 100 ° C (122 to 212 ° F).
1. INSPECT IGNITION COIL AND SPARK TEST
- (a) Check for DTCs.
NOTICE:
If a DTC is present, perform troubleshooting in accordance with the procedure for that DTC.
- (b) Check whether sparks occur.
- (1) Remove cylinder head cover No. 2 (See page IG-9).
- (2) Remove the 4 ignition coils (See page IG-9).
- (3) Using a 16 mm (0.63 in) plug wrench, remove the 4 spark plugs.
- (4) Install the spark plug onto each ignition coil and connect the ignition coil connectors.
- (5) Disconnect the 4 injector connectors.
- (6) Ground the spark plugs.
- (7) Check that sparks occur while the engine is being cranked.
NOTICE:
- Ground the spark plug when checking it.
- Replace any ignition coils that have been subjected to any physical impact.
- Do not crank the engine for more than 2 seconds.
If sparks do not occur, perform the following procedure.
- (c) Perform the spark test in accordance with the following procedure.
- (1) Check that the wire harness side connector of the ignition coil with igniter is securely connected.
Result
| Result | Proceed to |
|---|---|
| NG | Connect securely |
| OK | Go to next step |
Table Caption: This table outlines the next action to take based on a given result. An "NG" (Not Good) result leads to connecting securely, while an "OK" result allows progression to the next step.
- (2) Perform a spark test on each ignition coil with igniter.
- Replace the ignition coil with igniter with a functioning one.
- Perform the spark test again.
Result
| Result | Proceed to |
|---|---|
| OK | Replace ignition coil with igniter |
| NG | Go to next step |
Table Caption: This table outlines the next actions based on a test result. If the result is "OK," the ignition coil should be replaced with an igniter. If the result is "NG," proceed to the next step in the process.
- (3) Check that the power is supplied to the ignition coil with igniter.
- Turn the engine switch ON.
- Check that the battery voltage is applied to the positive (+) terminal of the ignition coil (See page ES-172).
Result
| Result | Proceed to |
|---|---|
| NG | Check wiring between ignition switch and ignition coil with igniter |
| OK | Go to next step |
Table Caption: This table outlines diagnostic steps based on the "Result" of a check, directing the user to either "Check wiring between ignition switch and ignition coil with igniter" if the result is "NG," or to "Go to next step" if the result is "OK."
- (4) Check the resistance of the camshaft position sensor.
Standard resistance
| Temperature | Specified Condition |
|---|---|
| Cold | 1,630 to 2,740 Ω |
| Hot | 2,065 to 3,225 Ω |
**Table Caption: This table outlines the specified resistance ranges for a component at different temperature conditions: a cold temperature requiring 1,630 to 2,740 ohms, and a hot temperature requiring 2,065 to
