You are watching: 2006 nissan altima crankshaft sensor location
Ok i got a 2006 altima 2.5l and had to change the CPS sensor.. I could not find a good DIY so here you go, the damn STEALER wanted 300.plus to do this.. Hell with that... Remove the (4) allen head bolts that hold the plastic engine cover. Remove the air tube that connects the throttle chamber to air filter box. Pull off the valve cover breather hose with the air tube. Now place a drop light under the two rubber heater hoses (at the firewall on the drivers hand side), shining the light forward towards the back side of the block (below the intake runners). To see the crankshaft sensor and connector, look between the valve cover and the throttle chambers (intake runners) on the drivers side, look straight down toward the ground… look for the sensor with a black wire connector with a green tab on the side, held to the engine block with a gold colored 10mm hex headed bolt. You will need to view the sensor from this position as you are following the steps below to remove and install the crank sensor.
You will have to push on the green part of the clip till you here a CLICK. Then just pull it off of the CPS. Mine just pushed in no prob, yet if it is hard try putting a 15mm socket on your thumb and try again so it wont cut into your thumb it will look like this when it comes off.
Next step is to get the CPS out of the side of the block, this was the hardest part for me.. Its a 10mm bolt holding it in, i took a 2in extension and reached down and put it on the bolt. then took a 4-6in extension and rachet and hooked to the already started 2in and socket and lossen it up.. Now to get the CPS out of the block you might be able to wiggle it back and forth to get it out, mine i took some needle nose pliers and grabbed it and pulled it out..

next to clean connectors and put in new CPS.. lube up the new O ring with oil slide it in the side of the block,,, then get the 10mm bolt through the sensor and into the block, kinda tricky! and torque it down think it is 8ft pounds mine is snug
