the manual says if i disconnect a vacuum line at idle and check the o2 sensor wire to batt gnd the voltage should drop to low range, but mine goes up to .9 or so volts. what gives? im getting a code 24 and code 21. 24 is the tps voltage high or low which i replaced and noticed deff improvenmts in running and shifting, 21 is the o2 sensor not reading rich or lean.. but im still getting both codes. i started going thru the rest of the checks n thats when i got the backwards operation. it does fluctuate between high and low when the vacuum line is connected like its supposed to. im off to check the wires to the ecu
another interresting note. my temp sensors dont operate in the range specified in the manual...what gives? testing with the engine warmed up i still get 3k ohms resistance, even the new one. the book says it should be under 1k ohms if warmed up.
thanx for ur help
