HEATED OXYGEN SENSOR (HO2S) REMOVAL/INSTALLATION [L3]
| WARNING | A hot engine and exhaust system can cause severe burns. Turn off the engine and wait until they are cool before removing the exhaust system. |
Scheme 15
- Remove the battery cover. (See «BATTERY REMOVAL/INSTALLATION [L3]»(ref-292887-S30644836642008080600000) .)
- Disconnect the negative battery cable.
- Remove the plug hole cover.
- Disconnect the HO2S connector.
- Remove in the order indicated in the table.
Scheme 16
Scheme 16: HO2S Removal Note
- Remove the HO2S using the SST.
Wiring Harness Bracket Installation Note
Note. There might be no pin. If there is no pin, lock the wiring harness bracket against rotation and tighten the nut.
Scheme 17
- Remove the battery cover.
- Disconnect the negative battery cable.
- Perform the following procedure for easier access. Remove the under cover. Remove the splash shield.
- Disconnect the CKP sensor connector.
- Remove the CKP sensor.
Installation
| CAUTION | When foreign material such as an iron chip is on the CKP sensor, it can cause abnormal output from the sensor because of flux turbulence and adversely affect the engine control. Be sure there is no foreign material on the CKP sensor when replacing. |

Scheme 19
Scheme 20
- Perform the following procedure so that cylinder No.1 is at TDC. Disconnect the drive shaft (RH) from joint shaft, set the drive shaft (RH) out of the way. (See «DRIVE SHAFT REMOVAL/INSTALLATION»(ref-292914-S37901508222008080600000) ) Remove the cylinder block lower blind plug and install the SST. Rotate the crankshaft pulley clockwise until the crank weight contacts the SST so that cylinder No.1 is at TDC.
- Fit the center of the CKP sensor with the fifth tooth (counting counterclockwise from the empty space A as shown in the figure) of the pulse wheel.
- Install the CKP sensor fitting bolts.
- Remove the SST then install the cylinder block lower blind plug.
Scheme 21
Scheme 21: Air Gap Inspection
- Verify that the CKP sensor is securely installed.
- Using a thickness gauge, measure the air gap between the plate projections at the back of crankshaft pulley and the CKP sensor. If not within the specification, inspect the plate projections for cracks or bending. If there is any malfunction, replace the Crankshaft pulley. CKP sensor air gap 0.5-1.4 mm {0.02-0.05 in}
