Hi everyone. I replaced my water outlet valve a week ago and afterwards I'm getting these codes and a cooling fan running high speed. Codes are as follows.....PO 134, PO 135, PO237, AND PO 097. I messed up and changed valve w/o disconnecting negative cable but have sense disconnected and discharged any energy before reconnecting. What an I missing still???? Thank you!

Did you use a GM water outlet or an aftermarket one?

I would suggest to make sure all of the wiring connections are made. Maybe disconnect and reconnect the various sensors you touched.

That could possibly be you problem. The water outlet came with a sensor pre-installed, correct?

 

[Cruzewoeisme]

Yes it did. I was thinking maybe it was bad so I put the one I just installed 2 months ago in there hoping that was the issue.

 

[Cruzewoeisme]

Do you think using a spray contact cleaner on the connections would be any help? I just can't believe that 4 different sensors all went bad after I did the install. 2 O2 sensors, turbo pressure, and another I forget at the moment.

More than likely the sensors aren't your issue if you've put four of them in. If the ECM is getting a realistic reading from the sensor, the connection isn't the issue either. Do you have the ability to access sensor data?

 

[Cruzewoeisme]

Unfortunately, I do not have that ability. I also can't seem to find anyone else who has experienced this issue. I may have to suck it up and pay the dealership pricing. (Insert stomach churning noise here). Ugh

There are 3 different ways to approach automotive troubleshooting depending on the level of investment you willing to put in.

1. You can chase parts, where you use, "semi educated guesses," to replace parts until you replace the part or parts that are causing the problem. (Can get expensive, frustrating, and time consuming)

2. You can buy tools and diagnostic equipment and learn how to use them to figure out which part or parts are causing the problem. (IS expensive, time consuming, can be frustrating, but is extremely rewarding)

3. You can pay a trained technician, who already has the diagnostic equipment and the knowledge to use them, to diagnose the problem for you. (Most of the time, this is the easiest route)

This being said, I use option #2 and sometimes even use option #3 depending on my level of frustration, as I am not a professional technician.

The sensor in the outlet is the engine coolant sensor. It set a code when you refilled the coolant. I remember this happening when I did the water outlet.. Bleed the air out of the radiator tank on the white screw on the passenger side radiator tank.

Reset the codes..

Best thing I've heard in a while!! I'm headed home now and will get to it. Thank you!!

I would also pull apart the connectors and clean with contact cleaner and then blow them out with compressed air. If any coolant got in there it can short out the connectors.

 

[Cruzewoeisme]

I used compressed air last week but I will clean them as well this time. Thank you for your input! I appreciate all that I get!

For the P0097, @Blasirl has a nice post here: 2012 1.4T - tons of intake related codes

When replacing the outlet, did you unplug the blue O2 sensor cable? I think it hangs on to it, so it is likely you may have. It's also hard to seat back in, are you sure its seated correctly? I can provide pics if needed.

Lastly, you did the water outlet, not the thermostat, correct? Drivers side of the engine.

 

[Cruzewoeisme]

Yes correct. Water outlet valve on driver's side. Not thermostat.

 

[Cruzewoeisme]

And yes, I unhooked the blue O2 sensor

 

[Thebigzeus]

And yes, I unhooked the blue O2 sensor

ah ha! have we determined the root cause of the issues here?

 

[Cruzewoeisme]

I'm about to find out in about an hour. I'm just allowing some cool down before I go messing again.

 

[Thebigzeus]

Well
