Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
LH Side
- Connect the coupling harness and install the knock sensor using a claw-foot wrench.NOTE:
- Knock sensor must be positioned so that the connector center comes within the range shown in the figure.
- Make sure that the knock sensor and its connector do not touch the adjacent parts.
Tightening torque:
Calculation formula
T= 25 N.m (2.5 kgf-m, 18.4 ft-lb) x L1/(L1+L2)
T: Reading of the torque wrench
L1: Effective length of the torque wrench
L2: Effective length of the crowfoot wrench
NOTE: If the effective length of the tool used is unknown, consult the manufacturer of the tool. - Install the clip (D) and clip (E), and connect the connector (C).
- Install the engine wiring harness stay and install the clip (B).
Tightening torque:
19 N.m (1.9 kgf-m, 14.0 ft-lb)
- Install the engine ground and the harness case.
