there is no crankshaft in an rx-7, it has a rotary engine C12 - actually there is, its called a crank angle sensor but it is located on the block and measures the eccentril shaft (which is the equivilant to a crankshaft). if you look at the biggest metal pulley at the bottom of the engine the crank angle sensors are on the side of the strange looking metal plate on this pully, two short stuby looking things.
The tone rings for the crank and cam position sensors are different and the engine will not run.The tone rings for the crank and cam position sensors are different and the engine will not run.
possibly the crank angle or cam sensors Or injectors
The crank position sensor is located on the front of the engine, behind the lower crank pulleys.
On crankshaft position sensor, one camshaft position sensor.
You adjust the timing by moving the crank angle sensor. The crank angle sensor is driven by the camshaft closest to the intake manifold (passenger side of the engine) and is located behind the cylinder head and valve cover. Losen the bolt that secures the crank angle sensor, in order to move the crank angle sensor.
Crank shaft position sensors (2)
The crank angle position sensor on a 1994 Mazda 929 is typically located near the engine's crankshaft, often mounted on or near the timing cover. It may be positioned close to the harmonic balancer or timing belt, depending on the specific engine configuration. To access it, you may need to remove some components for better visibility and reach. Always consult the vehicle's service manual for precise location and removal instructions.
crankshshaft and camshaft position sensors are on the right rear driver side of the engine
check crank angle sensor
BG
It has a crank reference sensor by the crank pulley that adjusts timing and a #1 position sensor were trans and engine meet on left side of engine that starts spark sequence.
Crank angle sensor reads rpm and sends the signal to the ECU (computer) to aid in the calculation of engine rpm, ignition timing, fuel injection and crankshaft position.
