If I knew what you were working on I might be able to help more. On most cars and trucks with electric fans the fuse can be located in one of two places. check your owners manual for the location of the fuse. If the fuse is good, your on to the next step. The temp. sensor most likely "Calls" for the fans to come on through the "Computer." If this is the case then you may have a bad Relay. The "Computer" cannot control a high current device such as a fan, directly. Most manufacturers put a Relay somewhere in the Engine Compartment that the "Computer" engages, thus causing the Fans to come on. If the Fuse is Good and the Realy tests good then you need to look at the sensor itself. In most cases trying to test the sensor causes damage. If you determine or "approximate" that the sensor is At Fault then just go to your auto parts store and buy a new one. They aren't that expensive. If you get back to me with the Year, Make, and Model, I may be able to get a little more specific.
Crank angle sensor
No it will not. YOU have another problem.
A bad throttle sensor can cause engine jerking and rough running. A test of the computer codes should show if there seems to be a problem with the sensor.
its electronic cause of the distributorless ignition.
I don't believe the 03 S-10 uses an etc (electronic throttle control) sensor.
running rich, cause by bad O2 sensor and/or bad cats.
code 43 except2.2or2.5 4flashes pause 3flashes electronic sparkcontrol knock sensor circuit probable cause faulty knock sensor or mem_cal.
this can be cause by the crank position sensor if the fuel pump is running well then the only thing that cold cause the problem is crank position sensor
Podsible, if the sensor is so worn as to not send the right signal to the ECU the fuel/air trim will be off and indeed can cause a misfire from running to lean or too rich. The ECU does not know if the sensor is bad, it only knows what micro voltage it is "told" by 02 sensor
there should be a electronic plug on your gearbox, unplug that and screw out the sensor, but make sure its not the reverse sensor, if its the st or sport then its the abs sensor but that wil make you dash lights come on and show no milleage
