Installation Guide
⏱️ 3-Step Quick Replacement (No Oil Drain Required):
Step 1: Remove Old Sensor
-
Operate on COLD ENGINE CONDITION.
-
Loosen old sensor counterclockwise (Torque ≤ 30 N·m).
-
⚠️ CRITICAL! Use a magnetic retrieval tool to extract residual metal debris (80% failures caused by debris).
Step 2: Install New Sensor
Step 3: Wiring & Verification
Red wire → 24V+
Black wire → GND
Yellow wire → ECU signal terminal (Pin #32)
Post-Install Test:
Technical Notes
-
Sealant Tip: Apply PTFE tape clockwise to prevent unraveling during installation.
-
Torque Sequence:
-
Signal Validation:
0.15 MPa = 0.2V (alarm trigger point)
0.50 MPa = 1.8V
10.0 MPa = 4.5V
