The choke position sensor in a 2008 Chevy Colorado is situated on the admission complex in the motor compartment. The choke position sensor (TPS) is important for Your vehicle's fuel the board framework and guarantees that the right combination of air and fuel is conveyed to Your motor. The TPS gives the most immediate sign to the fuel infusion arrangement of what power requests are being made by the motor. At the point when a TPS turns sour,then,at that point,the vehicle's choke body won't work as expected. It could either remain shut or it won't close as expected which is an extreme issue. In the event that it stays shut then Your motor isn't going get air and it won't start.The normal expense for a choke position sensor substitution is somewhere in the range of $170 and $220. Work costs are assessed somewhere in the range of $60 and $70 while parts are valued somewhere in the range of $110 and $150.
