It's by (above) the driver side rear wheel.

Make sure you depressurize the system before removing the filter or you will gas all over the place.

The front impact sensor is located under the vehicle, towards the center/driver's side. Best access is from under the vehicle with the front air deflector removed.

  • Remove the front air deflector.
  • Remove the connector position assurance (CPA) (5) from the front end sensor wiring harness connector (4).
  • Disconnect the front end sensor wiring harness connector (4) from the front end sensor (1).
  • Through the access hole located in the bottom of the lower tie bar, loosen the front end sensor mounting fastener (3).
IMPORTANT: The front end sensor mounting fastener (3) has left handed threads.
  • Remove the front end sensor (1) from the lower tie bar by lifting upward and sliding rearward out of the key hole slot (2).

Did you purge the master cylinder on the bench before installing, all line should be plugged except one and that one has a piece of tubing that goes back into the reservoir. The process has to continue until all the air is purged. Install, remove the plugs ( don;t worry about a small amount of fluid leaking as the lines are installed. I use plastic bottle filled about 1/3 full set on the ground, run a piece of tubing from bleeder valve into bottle. Install at right rear, crack the bleeder valve and pump the brake pedal slowly while a 2nd person keeps the reservoir full, they will also observe the bottle until all the air is purged, close bleeder and move the left rear and repeat, next the right front and finally the left front. Do not reuse the fluid is expelled. If this seems a little hard( It is really very easy) buy a mighty vacuum and pull the fluid thru the lines in the order of right rear, left rear, right front, left front. DO not let reservoir get low or you will spend all day starting over.

Go ASAP to a repair shop. Most offer a free brake inspection. When the brakes will not "pump up" it is usually a bad master cylinder that is by passing internally( it will still be full of fluid) or an hydraulic leak in the system (the fluid will be very low or empty). Do not take a chance of having an accident.

First, have you tried spraying starter fluid into the throttle body to see if it is a fuel problem? Have you checked to see if there is a strong spark at the plugs? Hook up a scanner and see if the obdll system is working. That may tell you which wires are not connected .
