1996 HONDA ACCORD CRANKSHAFT SENSOR AND CAMSHAFT SENSOR.

I seriously doubt it. Sometimes the crankshaft or camshaft sensor fails and the other is used by the ECU to get you by. Many vehicles do not do this. The ECU uses this for spark plug firing timing and is critical...

My info shows the crank sensor takes its reading from the front end of crankshaft. You will have to remove crank shaft pulley and timing belt cover to get at it, according to my info.

It may be easier to get at front of crankshaft through passenger side wheel well?

REMOVAL & INSTALLATION

4.3L, 5.0L, 5.7L and 7.4L Engines
See Figures 1, 2, 3, 4, 5 and 6

1. Remove the timing cover. This will allow access to the timing chain.
2. Crank the engine until the timing marks on both sprockets are nearest each other and in line between the shaft centers.

Fig. Fig. 1: Crank the engine until the timing marks on both sprockets are in line

1. On 1996-98 vehicles remove the crankshaft position sensor reluctor ring, if equipped. On 7.4L engines tool J-41371 or its equivalent puller must be used to remove the reluctor ring.
2. Take out the bolts that hold the camshaft gear to the camshaft. This gear is a light press fit on the camshaft and will come off easily. It is located by a dowel. The chain comes off with the camshaft gear.

Fig. Fig. 3: Remove the camshaft gear and timing chain
A gear puller will be required to remove the crankshaft gear.
To install:

1. Without disturbing the position of the engine, mount the new crankshaft gear on the shaft, and mount the chain over the camshaft gear. Arrange the camshaft gear in such a way that the timing marks will line up between the shaft centers and the camshaft locating dowel will enter the dowel hole in the cam sprocket.
2. Place the cam sprocket, with its chain mounted over it, in position on the front of the truck and pull up with the three bolts that hold it to the camshaft.
3. After the gears are in place, turn the engine two full revolutions to make certain that the timing marks are in correct alignment between the shaft centers. Tighten the camshaft sprocket bolts (and nut on the 4.3L) to 21 ft. lbs. (28 Nm) on 1988-95 models. On 1996-98 models, tighten the bolts to 18 ft. Lbs. (25 Nm). On the 7.4L, tighten them to 20 ft. lbs. (26 Nm) on 1988-95 models. On 1996-98 models, tighten the bolts to 25 ft. Lbs. (34 Nm).

When installing the crankshaft position sensor you must use install a new oil ring seal onto the sensor.

1. Install the crankshaft position sensor reluctor ring (if equipped), onto the crankshaft until it is firmly seated against the crankshaft sprocket. On 1996-98 7.4L vehicles replace the reluctor ring with a new component.
2. Install the front cover, torsional damper, water pump and the radiator.

Check crankshaft and camshaft position sensors.

Use an scanner to read any ECU trouble codes.

In this case the solenoid needs to be replaced.The error code in this case is P1533.This code is many a times noticed on Mercedes Benz.

Assuming you have the 2.3 L 4 cylinder engine, the CYP sensor [Honda does not call it a camshaft sensor] is located in the distributor. It also has 2 crankshaft sensors, located down at the front of the crankshaft. You need to remove the timing belt covers to access those.
FYI, P1259 is a VTEC system [variable valve timing] malfunction code. First step would be to change the engine oil and filter. Dirty oil can cause the VTEC solenoid to stick.

p1391= crankshaft / camshaft position sensor intermitant signal, check, wiring, connections & sensors
p1398= engine control system missfire detection limit reached probable causes, wiring,poor connections,engine mechanical fault,ignition/fuel system fault (causing misfire) or camshaft/ crank shaft position sensor

have scanned to find problem code to get an idea of what it is. .it may either be the crank or cam sensor, check the crank sensor first. if it is bad it sends wrong timing info to pcm. therefore jeep will not start!! It is either the camshaft or crankshaft positioner. I would check the crank pos. first. Zach Cabot, AR

There are two cam shaft sensors and one crank sensor Nissian did sell a kit at one time with all the sensors in it one cam sensor is in the left cylinder head a one is in the right cylinder head

camshaft sensor is in distributor(requires dist. replacement) crankshaft is behind lower timing belt cover
