Recently my dash 'check engine' warning light came on. After paying for a diagnostic it was found that the cause may be either a faulty heated oxygen sensor(s) and/or a missing or damaged exhaust manifold gasket. It says, carry out a self test using a star tester(up to 95 MY inclusive) or FDS 2000 (from '96 MY). If the codes read off indicate too weak or too rich mixture, then install a new, modified exhaust manifold gasket, carry out a road test and measure the control value of the heated oxygen sensor(s). If the measured control value of the oxygen sensor(s) is more negative than -0,15V (e.g-0,5), renew the oxygen sensor for the cylinder bank affected.
Now the problem I have is that the Ford Explorer is possible the most uncommon car in the United Kingdom. As a result of which if I take this to the main dealer, they have quoted me £617 ($987) to do the job.
The question is can I do the above?
Perhaps if any one could answer some of the following questions and advice me if I should pay the money or have a go myself.
Questions.
1) What is a heated oxygen sensor.
2)What is a star tester or FDS 2000
3)Is it easy to replace the manifold gasket and the sensors.
4)How do I measure the control value of the oxygen sensors.
5)Where and what are the cylinder banks.
6)Do you know of any parts shops in the usa that I can buy over the web.
7)What is OBD 11.
If you can help, please do, yours Jim in the UK, incidently petrol is about $7 a gallon. I am now only getting 15 to the gallon. Ouch
