Location of high voltage wires on the engine
Incorrect installation and placement of high-voltage wires on the engine can lead to spark jumping from wire to wire or to ground, which, in turn, can lead to misfires and a decrease in crankshaft speed when the car is moving at high speed.
Therefore, install the high voltage wires properly as shown in the figures.
Examination
1. Clean and check the integrity of the insulation of the high-voltage wires. Check the inner surfaces of the contacts of the high-voltage wires for corrosion or carbon deposits.
2. Use an ohmmeter to measure the resistance of the high-voltage wires.
Note: The resistance of the high-voltage wire should not exceed 10,000 ohms, otherwise replace the wire.
High voltage wires
| High voltage wires | ||||
| Cylinder | №1 | №2 | №3 | №4 |
| Length, mm | 560 | 440 | 360 | 310 |
| Resistance (VOUv(), Ohm) | 2,51–3,76 | 1,97–2,96 | 1,61–2,42 | 1,39–2,08 |
| Resistance (R16AIPS), Ohm | 5,60–11,76 | 4,40–9,24 | 3,60–7,56 | 3,10–6,51 |
Troubleshooting
