If it is broken off below the bracket and you cant get it with a pair of needle nose pliers you will have to drill a tiny hole in the centre and thread a small screw into it for leverage.
If it broken above the retainer bracket, remove the single bolt and remove the sensor with needle nose pliers.
its not straight
The sensors are on the outside of the engine. The weather, heat and cold take its toll. They just basically wear out, and there is no way around it.
Yes
The crankshaft pulley has broken causing the outer ring to slide forward into the fan assy. replace your crankshaft pulley and all will be well
Piston seized to cylinder wall Broken Crankshaft
the engine wont run. it cranks funny
Crankshaft pulley turns with the crank, if it won't turn at all, something internally is broken.
Broken timing belt?
Usually, part of it will still be attached to the crankshaft. Sometimes, it will be in the oil pan.
No, but it can be replaced. I would recommend taking to a professional.
Some possible problems when your vehicle cranks, but won't start are a bad crankshaft position sensor, or a faulty ignition switch. Another possibility is a loose or broken wire that runs from the sensor to the PCM.
Both of these codes are for the crankshaft Position Sensor. You should look at the connector that plugs into the senosr to make sure you have no broken or frayed wires. If that ok you should take it to a mechanic.
