Crank Shaft Position Sensor Installation

Are the spacers critical?

Why not just run the nuts down to the base for the same effect?

 

DTC Error Codes

What Sensors can cuase the ECM to disable grounding for the Fuel Pump Control Relay and Spark Plug Ignition Coils?

With or Without CODES

I am pretty sure the the Crank Shaft Position CKP will

What about the Cam Shaft Position CMP?

What about the Temp and Oil sensors?

Emergency Fule Shut-Off switch but that usually generates a code

Mass Air issues will still allow fuel and spark as far as I know

Tranny and Transfer boxes will prevent the starter from engaging.

 

Hell yes the spacers are critical. That's why they are there.

Not sure where you are going with all this but it sounds like the last mechanic if you will call him that had no idea what he was doing and possibly caused the damn crank sensor to have problems.

You need to replace that with a good one and go from there. We have all told you that seems to be your problem.


Its not uncommon for some know it all tard monkey to attempt to fix one of these trucks and make the problem worse. I talked to a guy yesterday that just purchased a rover and come to find out it has a totally different drive shaft in it with no double Cardin joint on it, and the teeth of the slip are extended out so that they are visible and its about to fall apart. Another youngster that is driving his truck around with no bleed screw installed and coolant just flowing out when it is running. Who knows how long its been like that and how much damage has been caused. I think he stated he was off roading with it like that. Its silly but true

 

Its the lack of coeds that is the big problem. I found that you can un-mount the Crankshaft Position Seensor (CKP) and even disconnect it while the truck is running and there will still be absolutely no codes generated

Today I though I made some progress when I found the CKP cable was possible loose. After reconnecting I got a full day of driving and idling. However around 3:00 pm after an hour of idling it had stalled and was hard to restart. That one did come with a 02 sensor code P0154

I am going to check the CKP sensor connection again once it is cooled down.

Re: Mass Air I did mess with that and got a bunch of coeds but it did not stall the motor!!!

I mentioned in another post that it would be interesting to find out exactly what it take to put the ECM in shutdown mode.

 

Please review the pages I sent you in post 4 of this thread. And... btw - please tell the rest of us how all this under the hood work gets co-eds....

 

OK I am convinced that all this trouble is due to the Crankshaft Position Sensor or wiring to the ECM.

Would I be correct in sayin the CKS is the ONLY sensor that can actually turn the motor off? Every other sensor will still let the motor run to some degree. Loosing the CKS input will disable both the fuel pump relay and ignition coils?

Anyway truckt drove great all day, and idled for hours. This afternoon it stalled twice whil idleing but re-started of. This evening it cooled down and took several minutes of cranking to start.

Still no codes.

I will order another snesor and replacement spacers ASAP
I am also considering hardwiring past the sensor cable connector to eliminate that possibility.

SPACERS: the spacer(s) I was thinking are the ones over the mounting bolts outside of the sensor.

I take it the diagram was referring to the interanal cyclinder that the sensor rests on.

I will look for better diagrams.

Has anyone ever tried monitoring the AC voltage output of the sensor when cranking or running?

 

When replacing the CKP, the last step in RAVE says:
9. Reset adaptions using TestBook.

How the heck to I do that?

 

Oh... and to the original poster..

Did you check your IAC (Idle Air Controller)? Mine was sticking closed, causing mine to stall. A quick soak in carb cleaner free'd it up and I was on my way again. This will not throw any codes, it just cuts off the air supply to the engine when you take your foot off the gas.

 

You don't need testbook, plenty of posts on here for guys replacing the sensor DIY. The ECU re-adapts. There are some sensors that can cause engine to misbehave, and they are detailed in the Engine Management section of the workshop manual. If you don't want to read the RAVE, or the Bosch ECU manual, then you are doomed to working on your vehicle 140 characters at a time from the kindness of strangers. Here are several sensors under the bonnet that can stop or prevent engine running.

CKP - There is no back up strategy or limp home facility if this sensor fails, the engine does not run.

If the MAF sensor fails, the ECM implements a back up strategy which is based on throttle angle. Poor throttle response and reduced performance will result.

Should the IAT sensor fail, the ECM defaults to an assumed air temperature of 45 °C (113 °F).

If the TP sensor signal fails, the ECM uses a default value derived from engine load and speed.

In the event of an IACV signal failure any of the following symptoms may be observed:
Either low or high idle speed
Engine stalls.

Difficult starting.
Idle speed in default condition

In the event of a fuel pump relay failure any of the following symptoms may be observed:

Engine stalls or will not start.

No fuel pressure at the fuel injectors

In the event of ignition coil failure any of the following symptoms may be observed
Engine misfire on specific cylinders.
Engine will not start.

 

Could not have been said any better or any clearer.
