Edit: I just wanted to update that I fixed it. It was a simple fix from a simple mistake on my part. I must have gotten in a hurry when I was installing the PS bracket assembly.

I just got my new engine in and running, and the power steering isn't working. I did do some searching and read up on the MagnaSteering trouble shooting techniques. I haven't scanned anything for DTC's but I will asap.

This post it more of a precursor before I start to dive in and maybe get an idea if anything I did caused this. The PS was working perfectly before the new build.

I changed the EBCM sensor that plugs into the drivers side of the EBCM. This required a new pigtail harness that I soldered in. This harness had 3 white wires that I visually matched up to the current colored wires based on pin location of the old sensor harness. Could this cause my issue?

Also, I noticed that the fluid in my reservoir isn't even trying to circulate. I haven't tried the bleeding procedure, but I have turned the wheel back and forth quite a few times and driven the car with no improvement.

I've read that the ohms across the rack pins is somewhere around 2 ohms. Is that correct?

Any help is appreciated...

 

Raise the car up front wheels off the ground, turn your wheels all the way one way and shut the engine off make sure there is fluid in the reservoir and go and have a beer.
Come back and turn the wheels all the way the other way with the engine running, shut it off and top off the fluid and go and have another beer.
When you come back start the car and top off the fluid and turn wheels lock to lock a few times, shut off the engine and check the fluid level and top off as necessary.

 

Thanks for the tip, Bob.

My current DTC's are as follows:

DTC P0343 C-Camshaft Position (CMP) Sensor Circuit High Voltage
DTC P1515 H-Control Module Throttle Actuator Position Performance
DTC C1278 H-TCS Temporarily Inhibited By PCM

These are all new to the new motor swap. I have a couple others, but they are MAF related because it's tuned in SD and they are turned off.

 

Guys, today I removed the fluid from the PS reservoir and used a MightyVac to pull a vacuum on the system and I did hear a good bit of air bubbles at first. I let it sit and hold that vacuum for half an hour or so and filled it back up with fluid. I still do not have power steering and when I just drove the car down the road, it puked a little bit of fluid out of the reservoir.

I do still have the C1278 history code, but that may be from the P1514 code that sends me into Reduced Engine Power.

Anyone have experience with this issue?

 

I bled it according to the procedure I copied below. At #6, my MightyVac doesn't drop to 2-3 in/Hg, it just sits comfortably at 20 in/Hg. I took the belt off and used a pry bar lightly against the pulley but it doesn't seem to have any play. I spin it by hand and it is easy to spin. I spin the pulley and I don't get any bubbles or anything in the reservoir. I don't know if these are valid tests, but I just wanted to convey what I was working with.


Bleeding the Power Steering System
Tools Required
· J 35555 Mity Vac
· J 43485 Power Steering Bleeder Adapter
· Important
Use clean, new power steering fluid type only.
See the Maintenance and Lubrication subsection for fluid specifications.
· Notice
If the power steering system has been serviced, an accurate fluid level reading cannot be obtained unless air is bled from the steering system. The air in the fluid may cause pump cavitation noise and may cause pump damage over a period of time.
Notice
When adding fluid or making a complete fluid change, always use the proper power steering fluid. Failure to use the proper fluid will cause hose and seal damage and fluid leaks.
Important
Hoses touching the frame, body, or engine may cause system noise.
· Verify that the hoses do not touch any other part of the vehicle.
Important
Loose connections may not leak, but could allow air into the steering system.
· Verify that all hose connections are tight.
Important
Maintain the fluid level throughout the bleed procedure.
1. Remove the pump reservoir cap.
2. Fill the pump reservoir with fluid to the "FULL COLD" level.
3. Attach J 43485 to J 35555 or equivalent.
4. Place J 43485 on or in the pump reservoir filler neck.
5. Apply a vacuum of 68 kPa (20 in Hg) maximum.
6. Wait 5 minutes. Typical vacuum drop is 7-10 kPa (2-3 in Hg). If the vacuum does not remain steady, refer to Excessive Vacuum Drop Diagnosis at the end of this procedure.
7. Remove the J 43485 and the J 35555 .
8. Reinstall the pump reservoir cap.
9. Start the engine. Allow the engine to idle.
10. Turn off the engine.
11. Verify the fluid level. Repeat steps 9 through 11 until fluid stabilizes.
Important
Do not turn steering wheel to lock.
12. Start the engine. Allow the engine to idle.
13. Turn the steering wheel 180-360 degrees in both directions 5 times.
14. Switch the ignition off.
15. Verify the fluid level.
16. Remove the pump reservoir cap.
17. Attach J 43485 to J 35555 or equivalent.
18. Place J 43485 on or in the pump reservoir filler neck.
19. Apply a vacuum of 68 kPa (20 in Hg) maximum.
20. Wait 5 minutes.
21. Remove the J 43485 and the J 35555 .
22. Verify the fluid level.
23. Reinstall the pump reservoir cap.
