Crankshaft and camshaft position sensors

I have replaced these 2 sensors but after running around for 150 miles the light came back on with crankshaft position sensor again.

    Have you took your car into Nissan for the recall? Are you replacing it with the new Metal design position sensors? Are you replacing the right sensor?

MAke sure you replaced the right sensor and it's the proper design.(If you bought a generic part, it;s probably the wrong thing) I replaced my cam and crank sensors with the generic ones from AutoZone and they had no effect. Took it to Nissan, they replaced both at my expense, AND REPROGRAMMED THE ECU. That fixed that problem SES light hasn;t come on in 6 months....Fingers crossed

2007 Cadillac 3.6L srx, check engi, code p00017 crank sensor - replaced, still running rough and giving me a misfire on 1,3&5. Changed plugs, still 1,3&5 misfire - 155000 miles, could it need new coil


P0017 timing chain Chevy Colorado P0017 Case Study Part 1
155,000 miles This is not a DTC for the crank sensor . This is for variable valve timing .
DTC P0017: Crankshaft Position (CKP) - Exhaust Camshaft Position (CMP) Correlation Bank 1
The camshaft position (CMP) actuator system enables the engine control module (ECM) to change the timing of the camshafts while the engine is operating. The CMP actuator solenoid signal from the ECM is pulse width modulated (PWM). The ECM controls the CMP actuator solenoid duty cycle by controlling the amount of solenoid ON time. The CMP actuator solenoid controls the advance or the retard of each camshaft. The CMP actuator solenoid controls the oil flow that applies the pressure to advance or retard the camshafts.
Ignition voltage is supplied directly to the CMP actuator solenoid. The ECM controls the solenoid by grounding the control circuit with a solid state device called a driver. The ECM compares the camshaft position or the camshaft angle, to the position of the crankshaft.

Your a little out of your league on this ! Your best bet ,take it to a qualified repair shop !

• Inspect the engine for any recent engine mechanical repairs. An incorrectly installed camshaft, camshaft actuator, camshaft sensor, crankshaft sensor, or timing chain can cause this DTC to set.
• An actuator that is in the full advance or retard position can cause this DTC to set.
• The presence of DTCs P0008 and P0009 along with P0016, P0017, P0018, and P0019 indicates a possible condition with the primary timing chain and the alignment between both intermediate sprockets and the crankshaft. Or, the crankshaft reluctor wheel has moved and is no longer referenced to top dead center (TDC).
• Observing the desired and actual camshaft angle parameters, with a scan tool before a DTC sets, may help to isolate whether a condition is specific to one camshaft, one bank, or caused by a condition with the primary crankshaft timing.

the common causes for code P0017 are as follows:
  • A faulty cam or crank sensor
  • The cam or crank circuit is open or shorted
  • The timing belt/chain is out of time
  • The cam or crank tone ring is slipped/broken
  • A problem in the VVT system P0016 Crankshaft Position - Camshaft Position Correlation (Bank 1 Sensor A) P0017 Crankshaft Position - Camshaft Position Correlation (Bank 1 Sensor) God Bless! Hope this helps you.

How do replace ignition control module in 1998 K-1500 5.0 liter vortec


This system does not use the ignition module used on the DI systems in the past. The VCM controller now controls the ignition control (IC) and bypass functions.
The crankshaft sensor, located in the front engine cover, is perpendicular to a target wheel attached to the crankshaft. The target wheel is equipped with slots situated 60 degrees apart. As the crankshaft rotates, the target wheel rotates past the crankshaft position sensor. The rising and falling edges created by the slots cause a signal to be sent back to the VCM. This signal occurs three times per crankshaft revolution and is referred to as the 3x signal for V6 applications. The signal occurs four times per crankshaft revolution and is referred to as the 4x signal for V8 applications.
The VCM then utilizes this 3x (V6) or 4x (V8) signal in order to provide the correct spark to the engine by way of the single coil driver module. The single coil driver module is basically an electronic switch that when commanded by the VCM, causes the primary coil voltage to breakdown, energizing the secondary coil and providing a spark via the coil wire to the distributor cap. The distributor consists of the following components:
The system consists of the following components:
?€¢
Vehicle control module (VCM)


?€¢
Distributor


?€¢
Ignition coil driver module


?€¢
Ignition coil


?€¢
Crankshaft position (CKP) sensor


Now which part do you want to replace ?

?€¢
Cap and rotor


?€¢
Camshaft position sensor


?€¢
Gear drive and shaft

The camshaft drives the distributor shaft which rotates providing a spark to the correct cylinder by way of the cap and rotor. The camshaft position (CMP) sensor functions much like the crankshaft sensor previously described but provides only a 1x signal to the VCM. That is, for every 2 rotations of the crankshaft, there is 1 rotation of the camshaft. Note that the camshaft position sensor will not affect driveability. The sole purpose of the camshaft position sensor is to provide the VCM with the necessary information for the misfire diagnostic trouble codes (DTCs).
