ISUZU AXIOM: WHAT IS AN ION SENSING MODULE ON AN 03 ISUZU

Customer Question

WHAT IS AN ION SENSING MODULE ON AN 03 ISUZU AXIOM?
Submitted: 5 years ago.

Hello I will help you with your question,

 

The computer uses Ion sensing to determine when the spark was fired. This takes the place of a camshaft position and ignition failure sensor to let the computer know where the piston and camshaft is in its rotation.

 

This is used to fine tune when the spark plugs are fired.

 

Let me know what I can do to help you

 

Thank you

Thanks,are these sensors common to fail?My Modis isnt the most helpful diagnostic tool i have (although the most expensive)
Expert:  George H. replied 5 years ago.

Yes they are fairly common to fail as they have to be sensitive and be able to handle a secondary spike at the same time.

 

Do you have a code for the module? Ignition module?

 

 

 

 

Customer: replied 5 years ago.
I have a P1340 code which states Ion sense module cylinder id fault.
Expert:  George H. replied 5 years ago.

That is pretty clear for the module. With the expense be sure you follow all the troubleshooting in the chart below

Okay i know its been a couple of weeks since i posted this question but im just now getting back to this vehicle.I installed the ion sensing module and the vehicle runs no better.took spark plugs out(they were pretty fouled and didnt look that old) and installed new double platinum plugs. Vehicle started and idled okay but when attempting to raise throttle vehicle bogs out
Expert:  George H. replied 5 years ago.

If you have bogging on acceleration you can have a fuel delivery problem that is causing the misfire or it could be an ignition problem.

 

Do you have any test equipment? It is certainly cheaper to test than to install parts.

 

If you are not equipped with a way to test this it would be the least expensive route to pay an hour or two of labor to a shop that is equipped.

 

let me know so I can help you

 

Thank you
