sensors can still be faulty but no CEL,really depends how faulty they are & if they are outside the parameters the ecu is looking for.
its hard to have a guess at faulty sensors not knowing whats written on the skunk chip.
if u have a lot of solder on some joints,then check any joins that are side by side & possibility of sharp bits of solder poking thru whatever insulation u used.
can s300 run obd0 injectors?
so a friend told me that Perhaps my ECT sensor is failing. The ecu uses this sensor to adjust fuel enrichment for cold/hot conditions, which makes sense cuz my car takes a while for it to start when its cold, and check this out, if i crank engine over when cold, it will take about 10 seconds for it to start, and it starts real rough, but if engine is cold and i crank for like 4 or 5 seconds, stop for like1 or 2 seconds and try again it will start as soon as i crank motor again, but still very rough, but if my ect was bad could the ecu still read correct temp when datalogging? what temperature should my ecu read when motor is warmed up to operating temperature? and wouldnt i be running rich? cuz i still get good gas mileage and i dont see black smoke out of my exhaust.
