How 2 replace camchaf senser - 2006 Chevrolet Impala

Check catalytic converter mapp senser EGR valve o2 senser

not likely some cars have a nylon gear around diff but dosent give trouble often. try fuses, wiring and clocks in that order

Just ahead of the starter the knock senser just screws into the side of the block. The problem is it screws into the engine coolant and the coolantr will come out then you remove the old senser. even if you frain the raditor coolant will still be in the engine ( quite alot) and you'll need to catchir in some way. You can get about 2 gallons. The messly way to do it is to ( with the engine cold) loosen the senser till you can turn it by hand. With the new senser in th=your other hand remove the senser and quickly screw the new senser in. You'll almost certainly get coolant on you so be eady, covering your eyes and arms ( glasses and a raincoat) you do it quickly eniugh very little mess will be made. The plug just squeezes and pulls off. Knock sensers seldom fail but the connection and the wires do. Someone replaceing the startercan hit the senser and break it. Don't drop the senser as the fall can break it too.

need to go to nearest dealer to update tps and wcm

If the car doesnt overheat its fine. Radiator fans arent meant to be on all the time.

the light has to be turned of by a chevy specialist using a computer

depends on what they told you upstream sensor or down stream sensor if you are not sure do them both.

Yes. First, in the fuse block under the hood check INJ A fuse and INJ B fuse. INJ A fuse is circuit 1039 which feeds the coil. If the fuse is OK, replace the coil electrical connector. I stock 2 of these at my dealership because they are needed quite often.
FYI P1351 is an ignition coil control circuit DTC.

I had an Audi doing exactly the same. What happened was that through time, especially if the vehicle gets older with a higher milage, dust and dirt gets into the speedometer itself and causes all the small gears to get sticky. I opened it and lubricated all the small moving parts inside and all were ok. Try it before buying a new speedometer. (I'm talking about the speedometer clock itself) Hope this info might help.

I had the same thing it was a bad ground under the fuse box and a mix of bad wires and disturber.
