Caterpillar Code 164-11 Full Of Diesel

Disconnect fuel line and put on a 12 plastic tube on male fitting just slide over the threads and put into a 2 gallon container.

I asked the mechanic at a recent oil change to take a look, and he said it was nothing to worry about.

I was still a little concerned but let it go until after our next trip.

This past week we went on a vacation, and shortly after climbing a 3,000 grade on the way down the summit my engine lost power and went into limp mode.

I had a new code showing up that stated 164 2 1 Injector Pressure Sensor Erratic.

After stopping the coach and trying a few times it continued to stay in limp mode.

I talked with a mechanic friend and he said to unplug the sensor.

Once I did this the error code went away, and the coach ran fine.

I continued on our trip another 200 miles and it ran fine, although I kept the throttle very light.

Caterpillar Code 164-11 Full Of Diesel

I noticed while looking around that the fuel filter on the Recor system was only 13 full of diesel.

I pressed the air purge button and it made a lot of noise and sounded to me as though it was sucking air.

It re-filled to about 12 way with fuel and then dropped back down again.

When the engine is running this drops down to about 18 filled with fuel.

So first of all, could this low of fuel be allowing air in and possibly causing the error code Any ideas where to start with the lack of fuel Is there a pump in the tank not working possibly I had the fuel filter changed at the last service, under 300 miles prior.

Air in fuel system, low power and event code of 164-11 lnjector Actuation Pressure fault.

This code is telling you that your injectors cool themselves via: Diesel fuel and damage will happen with injector sticking because of heat.

Your event code of 164-2 is electrical connection which is starting to stand out on many engines.

Next take the fuel line going in to the Racor waterfuel filter and line going out of the Racor waterfuel filter and connect together removing the Racor Water fuel out of the fuel system.

Again note: that waterfuel is a add on by mfg and over time is causing lot of problems.

Do not worry about that filter missing but make sure your secondary fuel filter is a Caterpillar 1R-0751 very important that number filter is used and be a Caterpillar filter only.

Feel your Problem will be corrected at this point if not I can get you running without taken to service shop.

First thing in order we have to remove the air in the fuel system.

Again one thing your Caterpillar engine does not require a waterfuel filter but does require a caterpillar 2 micron 1R-0751 secondary fuel filter, and following maintenance changing engine oil and same time change the secondary fuel filter.

Going back after bypassing the Racor water fuel filter, you can go to back of your engine where you will see a hex fitting about 4 inch long coming off a elbow attached to engine head.

The Hex fitting is at a slant facing to left or passenger side.
