Ok my 1995 Ford is running like a lame mule. When going uphill it seems to be cutting in and out on the cylinders. very low power. the check engine light came on so I pulled the codes out. The results are as follows:

111: System Pass
211: HO2S System Indicates Rich
225: Knock NOT sensed during dynamic response test
332: Insufficient EGR Flow Detected

I'm not sure if my truck has the solenoid or not. Can anyone tell me if it has one and help me understand these codes so I can figure out what parts to get. Thanks

 

111 is from the KOEO electrical self-test.

211 is a CM code only and says you have a bad PIP sensor.

The 332 code could be from the CM or KOER self-test without kowing what the code was from as you did not say I can not make a comment.

The 225 code indicates the Knock Sensor (KS) signal to the PCM was not sensed during the Dynamic Response Test in the Key On Engine Running Self-Test.
Possible causes:
-- Altitude of 6,000 ft or higher.
-- Damaged Knock Sensor.
-- Open or short in harness.
-- Damaged Powertrain Control Module (PCM).

 

The 332 code is only from the Engine Running Test aka KOER self-test. Would I have to find the KS and trace the wires back to the PCM to see where the short is or if there is anything damaged? And what is the 173 code? was I right that it is the HO2S System Indicates Rich? I don't want to be buying parts I don't need. With all that being said, in your opinion, would any of these problems be due to a hydraulic ram coming up through the floor and tipping my truck on the driver's side?

 

DTC 332 in Key On Engine Running (KOER) indicates the EVP sensor input did not change after the EVR solenoid was instructed by the Powertrain Control Module (PCM) to open the EGR valve.

Possible causes:
-- Vacuum hose leaks.
-- Icing.
-- Obstructed vacuum hose.
-- Obstructed EVR solenoid filter.
-- Damaged EVR solenoid.
-- Damaged EVP sensor.
-- Damaged EGR valve.

I would not worry about the KS sensor until you get the rest of the codes fixed.
Where did the 173 code come from (KOER or CM)?
The right or rear O2, system indicates rich.

Please tell us more about the hydraulic ram coming up through the floor and tipping my truck on the driver's side?

I did not see any codes pointing to a HO2S sensor.

 

Check the O2 sensor wiring, and see if its mangled. If the computer thinks the system is rich, it will start pulling lots of fuel.

 

Talking about knock sensor so safe to assume 302?

To test the knock sensor (KOER) after the cylinder ID code is transmitted. Place a steel rod or shaft near the bottom of the knock sensor directly on the engine block (not directly on the sensor) but near it and with a light hammer, knock slowly on the end of the rod for 15 seconds.

The computer should advance out the timing during the Dynamic response test to create a ping but if everything isn't as it should be, ignition timing late to start with for example, or it just doesn't load it enough to create a "ping" that code will appear.

It doesn't necessary mean there is a problem with the KS, might be yea but might be it just didn't ping when you floored it. You did floor it then let of when directed to do so during the KOER test correct?

I wouldn't worry to much about getting that code unless you do know it suffers from spark knock and nothing you've tried has corrected the problem. For starters would want to verify base timing and make sure someone didn't set it well beyond 10deg BTDC, if you haven't already that is.

You didn't mention 173 in your original post, if you get that one combine with 211 it be understandable.

211= Two or more successive erratic Profile Ignition Pickup (PIP) pulses occurred, resulting in a possible engine miss or stall.

Suffering enough missfires would tend to cause a rich condition, 173= HEGO sensor circuit indicates system rich

332= EGR valve opening not detected. Not a big problem in of itself provided the valve is fully closed and remains that way.

You can put that issue on the back burner if it is, if you suffer spark knock though you will want to address that once you've corrected the main problem. If not you do not have a spark knock problem? fix it or not otherwise is up to you then.

 

Thanks again for your support.

The story behind the ram incident is as follows:

I was using a friends garage to do some repairs. Not realizing that there was part of an old lift still left in the floor. I turned the compressor on and put my truck inside, but when the compressor had built up enough air the old ram let go and shot up out of the floor. Striking the exhaust and chassis, it came up so quickly that I didn't have a chance to get out. It lifted my truck up on one side to the point where it tipped over on it's side and the truck was left hanging on the edge of the ram. Luckily there wasn't a huge amount of body damage. But shortly after I started having trouble. That's why I am wondering could some of my trouble be a result of this mishap.

And I apologize when I put the original post up I messed up the codes so I will put them in again. They were all on the KOER self-test

111 System Passed
211 Profile Ignition Pickup Circuit Failure
173 HO2S System Indicates Rich
225 Knock NOT sensed during Dynamic Response Test
332 Insufficient EGR Flow Detected

 

As noted above the 211 is not a KOER code but a CM code.
This would be either bad engine harness wiring or a bad PIP sensor inside the distributor.
With the 211 we see on here 99% of the time it is a bad PIP sensor inside the distributor.

The 173 code may be from bad wiring under the truck from the ram. Very seldom when we see someone change out the O2 sensor that it has ever fix this code. Most of the time as pointed out above it is something else causing the code.

The 111 System passed is from the KOEO electrical test that checks the wiring and to see if all of the sensors are with in the ball park range of the sensor voltage wise.
So it is hard to see that you would have any electrical problems with the wiring to the O2 sensor. The PIP is a difference story as it is an off and on electrical switch.
The same goes for the KS as it is also an off and on electrical switch.

The 332 is bad vacuum lines most of the time but some times it can also be a bad EGR solenoid.

 

Did you you just write it up that nice or from a source? if so could i get that source? looks interesting

 

If you are talking about post #8 above I just wrote it up and did not use a source.
In post #2 & post #4 some of the posts was from the Ford 1995 Engine/Emissions-Diagnosis Shop Manual.

 

Wow yea the ram incident is new information, just plain lucky you weren't hurt or killed the truck might have rolled onto you as you got out of it.

That thing should have been disabled or at a minimum a proper safety installed so that sort of thing can't happen.

As suggested check the underside of it for damage to the wiring harness from the ram and or damage to the exhaust pipe and sensor. Did it crush bend fold or otherwise mutilate any of the pipe?

 

where can i find this manual?

As per the ram it was supposed to be disabled. But I'm assuming that when the hole got filled with cement it created a seal and when the air built up it shot out of the floor. As for the damage to the truck, it did crush the converter and both engine and transmission mounts got torn off. In my recent post I also asked if I should replace my PCM as it was mentioned it may be damaged. Also is this PCM located under the dash behind the glove compartment?

 

The PCM is located in the drivers kick panel and comes out under the hood or to be more exact it comes out through the a gap you make between the fender and the inter fender.
