check the air pump on your trailblazer, make sure its clean inside and the hoses are properly fastened. also check to make sure it works properly by listening for it when you start the vehicle. if the air pump is working correctly, replace the position 1 o2 sensor meaning the sensor on the exhaust manifold. the air pump is located under the vehicle, inside the frame rail on the drivers side in front of the transfer case crossmember with 2 hoses connected to it.

it wont HARM anything, but the emmision system will not work as designed. If there is no emission testing in your area, I would not worry about it.

the air pump is located on the engine towards the front of the vehicle and has apx. 3/4 diameter pipes running to and from it. it is apx. 2 fists in size and it is black plastic. one of the lines on top of the air pump runs to the other side of the engine towards the firewall. at the other end of that pipe is the valve. disconnect that pipe while the vehicle is running. no air out of the pipe means bad pump. air coming out of the pipe means bad valve

This code indicates the secondary air injection pump may not be working correctly. The pump is located on the front passenger side wheel well. Turn the front wheels sharply to the right and remove the plastic cover on the wheel well. Don't waste time trying to preserve the plastic clips. It takes a special tool to remove them and it is easier to purchase new clips at Auto Zone for $3.99 a pack. The pump is bolted on using three 12mm bolts. Remove the inlet tube and exhaust hose from the pump. The pump is wiring is connected directly to the motor with a two foot extension. The cable is feed through the same hole the outlet tube is in the fender well. It is terminated into a simply connector located on the front passenger side of the engine. Remove the motor from inside the fender well. Remove the bolt located in the center of the plastic cover. Remove the bolts located on the corners of the housing. Inspect the blower for wear and moisture. Clean as necessary. Attach an extension wire to your battery. Please use caution before attaching them to the fan wires. The fan spine at high RPM's and it may startle you at first. Obviously if the fan turns it works move forward. If it doesn't there may be binding, carrions, or the motor is burned out. Inspect and repair. The worst case scenario is the small motor may need replaced. This project will take about 2 hours to perform but it is worth your time verses the cost the dealer will charge you. On a technical difficult scale of 1 -10 ten being the highest....this procedure is about a five.
