Questioni had my 99 land rover tested this am. because the check engine light is on they said it showed a crank sensor and o2 sensor driver side above and below converter,are these easy to install for me to do.
AnswerHi Anthony,
yes, both are relatively easy to install.
Sensor - crankshaft position (CKP)
Remove
1. Release fixings and remove battery cover.
2. Disconnect battery earth lead.
3. Raise front of vehicle.
WARNING: Do not work on or under a vehicle supported only by a jack. Always support the vehicle on safety stands.
4. Release fixings and remove underbelly panel.
5. Release CKP sensor multiplug from bracket.
6. Remove 2 bolts securing CKP sensor heat shield and position aside.
7. Remove 2 nuts securing CKP sensor, remove
2 spacers, CKP sensor and sensor mounting.
8. Disconnect CKP sensor multiplug from engine harness.
Refit
1. Ensure all components are clean.
2. Connect CKP sensor multiplug to engine harness.
3. Fit sensor mounting, CKP sensor, 2 spacers and tighten CKP sensor retaining nuts to 6 Nm (5 lbf.ft).
Sensor - heated oxygen (HO2S) - pre-catalytic converter
Remove
1. Raise vehicle on a ramp.
2. Release HO2S multiplug from support bracket.
3. Release HO2S harness from clip and disconnect multiplug from HO2S.
4. Using a 22 mm crow's-foot spanner, remove HO2S.
CAUTION: HO2 sensors are easily damaged by dropping, excessive heat or contamination. Care must be taken not to damage the sensor housing or tip.
Refit
1. Clean sensor and exhaust pipe mating surfaces.
2. If refitting existing sensor, apply anti-seize compound to sensor threads.
WARNING: Some types of anti-seize compound used in service are a health hazard. Avoid skin contact.
NOTE: A new HO2 sensor is supplied pre-treated with anti-seize compound.
3. Fit a new sealing washer to HO2S
4. Fit HO2S and tighten to 45 Nm (33 lbf.ft).
5. Connect multiplug to HO2 S, and secure to support bracket and harness clip.
6. Lower vehicle.
Send me an email and I'll reply with some pics if you need them.
Best of luck,
