2003 chevrolet trailblazer 4.2 problem code p1481


See attached picture for location of temp. sensor, but that code has nothing to do with temp sensor. The speed of the fan does not agree with the commanded speed, you may have another bad fan clutch.

2002 trailblazer 4wheel - scan code p1484/p1481. Spent days researching these 2 codes on many web sites and forums> cooling fan speed signal lost only sometimes mostly in city not freeway. The car is...


Sounds like the fan clutch is going bad, these had a reputation for failing. The fan clutch is controlled by the computer and if the fan speed does not match what the computer has set, an error code is set. A fan clutch costs in the area of $120 - $200, and the labor to replace it is probably another equal amount.

Service engine light came on and we put in on a computer and it gave the code p1481 what does this mean


This is almost always the fan clutch. Years 2002-2004 are prone to fan clutch failure. Also a good idea to check out the harness for any frayed wiring.

Does the 2003 trailblazer have a on board diagnostic system? if so how do i activate it


yes, it's always active. A light will come on when it detects a fault. You can also use a good scanner to interrogate the system, actuate valves, etc.

Please see my tip at http://www.fixya.com/cars/r5932051-check_engine_light_check and let me know if you have questions.

What has to be done to turn off sevice engine soon light ? THIS IS ON A 2003 CHEVY TRAILBLAZER.


You can buy a hand scan tool and turn it off. If you can't get a scan tool, you can remove one of the battery cables and wait for 10 mins before hooking it back up. But keep in mind that you need to reset the radio and clock
