i got a 93 taurus, 3.0 engine, GL... i have the CEL on and went to auto
zone and got the free check engine light test:
25 Knock sensor, was told that i dont have one, i checked the car and
cannot find it????
34 EVP voltage out of range.. i took the sensor off and brought it to
auto and they tested it with pressure to the sensor and says it is good.
51 ECT sensor.. i checked it with engine cold and got a zero and open
signal so i guess this is correct and with the probles on the sensor at
hot engine i get 3.5 ohms at 20,000 ohms range.... is this correct or is
it defective???? i also pulled the small vacuum hose off the EGR and
let the engine idle which seemed ok for and idle and then pulled a
vacuun on it and then the engine stumbled(i think it is suppose to do
this???)... any ideas would be apprecitaed...the engine light comes and
goes as it pleases....
thanks for a reply.. if this message is repeated please excuse as i had
trouble with the newsgroup programs for the past two weeks..... and
tried to send it several times....
