Codes P1188 and p1189 after CCV replaced

Please clear all codes and with the scanner still connected turn the key to the on position without cranking the engine over to see what comes up. Does the engine run?

Cheers, Ken

The day after I posted I found the o-rings went bad on fuel injectors. Waiting for them to come in today to continue. Thinking there was a small leak I did not see, but not sure if it would set these codes.

Oh yes, it could cause all kinds of problems. Did the codes clear?

I got it back running cleared the codes and it came back. Here are recent freeze frames.

It has got bad lag causing traction to activate and rough start up idle and poor idle when stopped.

By these numbers is looks like the MAF is having an issue which can be caused by a MAF sensor problem or a partially clogged catalytic converter. Here are two guides to help us see what the problem is:

Please run down these guides and report back.

Could this cause traction control to activate?

Not really that would be a separate issue. Do you think that is what is slowing the car down? Can you make a quick video of the problem and upload it in your response so I can what is going on?

Sorry, I just saw this. I am more concerned with the check engine light. I got a new MAF and installed in no light, but I am getting this now:

These misfires appear when at idle.

How does the engine seem to run? If okay I would say the computer is having an issue. Please remove the PCM and look for water damage. If you clear the codes and then just turn the key on without starting the engine do any codes come up?

Runs much better than before, but will notice the mis at idle. I cleared codes key off and no code were present have not looked at PCM just yet.

The first code to pend is p1622.

This code is for the thermostat sticking open which can cause some issues. Can you please remove it to see if it is stuck open?

This guide will give you an idea for what you are inf for:

I will get needed parts and install. I will let you know how things go.

Sweet!

What is the possibility it is fuel related?

These codes are oxygen sensor related can you make the sensors are plugged in? Also, if you have the wiring connectors off of them or any other sensor please check then to make sure they are plugged into the right place. BMW does not have unique electrical connectors of each sensor. It could be fuel related like bad gas. How did it run before you did the repair?

About the same. I feel it is running worse because of this extreme heat.

I noticed a code for fuel pressure today as well p1250 code.

That can be a clue. Can you take a video of the way the engine running so I can see what is going on?

I can probably send you a live feed from module. Also, not sure if this could be related but my fuel gauge fluctuates while driving by almost a quarter tank.

I have also noticed it takes a second or two longer then normal for it to start up.

Can you take a video of the way the engine running so I can see what is going on? Use your phone and upload it here.

Yes, I forgot to do that.

Let me know if you need more my speedometer is currently inop 7.

If the speedometer is not working that would indicate the vehicle speed sensor is not working. Here is its location so you can swap it out.

It sounds like the engine is running good from what I could hear.

Check the plug maybe it got bumped in the repair somehow.

Check out the diagrams (below). Please let us know what you find.

I was under the impression the speed sensor was through ABS. I am waiting for s o bushing long story short bought the car for $24.00 knowing it was a project. $200.00 parts later and now sensors and electrical started up. Could this sensor cause these two returning codes? With random intermittent codes for misfire? I am getting the fuel pressure regulator this week just to be sure I am not afraid to dump money in it for new parts car sat for almost five years.

These kind of projects can snowball, but if the speedometer is not working that is job one because it can cause all kinds of additional issues the car must know its speed.

Okay.

So I went to replace the speed sensor that supposed to be on the differential and I cannot seem to find any harnesses or anything that looks like the sensor has be deleted. Is is possible the speedometer is read through right rear ABS?

I found more information that they put them to two places. Here is the one that is in the transmission. Check out the diagrams (below). Please let us know what happens.

Cheers, Ken

I am going to be getting an order ready. What would be best temperature wise to install for the thermostat?

I would go for the 192, because the computer needs to see heat to go into closed loop sooner.

Okay thank you. I noticed it is running around 226. Also getting a code p1622. So I am thinking I have a wiring issue as well.

It does sounds like a wiring issue. here is a guide to help you test the wiring and the engine wiring diagrams please make sure the wiring is going to the correct sensor because BMW does not use dedicated connectors:
