Sounds like one of the bolts holding the assy. in may be gone. Yes, to get it out you will have to pull it. I'd take a second look and see if you can't find what is wrong before you pull it. You can always look at the other side and compare the two. What year and model?

If you have had the P1133 error code on your newer model Impreza please post the fix. My 99 is seeing 3.8 volts with the O2 sensor wires disconnected. Another member has indicated the same. I have a ECU on the way. I thought this post may save someone the cost of the O2 sensor.

I have a good one and tail pipe. $20 to pack for shipping and you pay the shipping from 80916. Good CO parts with surface rust only. Lmdew@hotmail.com

I have a good set for the 93 Impreza. I think they are the same, but you'd have to try them to make sure. Legacy to Impreza. Lmdew@hotmail.com Colorado Springs.

I turn the cover plate over and bolt it in with 1 bolt. It forms a holder for the drive shaft. You can then drive the car on or off the dolly for limited distances. Take some liquid wrench for the cover bolts!

I'd pulled the wires out of the ECU plug and the ECU still sees 3.8 volts. There should be 0 volts there with no input, I would think. The ECU is all solid state and I did not see any burned/shorted circuits, but I'm not a micro-miniture repair guy either. Thanks for the thoughts.

I believe I have confirmed its the ECU. I pulled connector B136 pins 7 (white +) and 20 (black -) which are the O2 sensor input wires. The ECU still sees 3.8 volts and reading the O2 sensor direct its 0.001 to 0.8 volts which is right in the range is should be. How long is the Federal Specifaction Emissions Performance Warranty period? I thought it was 8 years, but have not been able to confirm it. I'll check with the Dealer to see if the ECU has any recalls. Looks like its a new ECU.

I'd try over at http://www.nasioc.com in the performance form.

I disconnected the O2 sensor in the engine bay. It worked fine if read directly. At the same time the ECU still had 3.8 volts. I pulled the ECU cover and looked at the circuits and no defects noted. I'm going to try another ECU or pull the O2 sensor wires at the ECU plugs and then see if the ECU still has 3.8 volts. That will confirm its internal.

Without it you will not have ABS and the light will be on!

Could be if the new axle did not have the ABS sensor ring or the wires got damaged.

Send me a PM or call 719-200-2973. My son has two spare starters in Fort Collins for a Auto Trans. He'd be happy to put one in for you. Later, Larry

Yep, that was my plan. I'm going to disconnect the sensor from the harness and see what the ECU has vs the output of the sensor. I just need the time to get there. Thanks for the info! I'll update when I get it checked.

I probe the splices of the new sensor with my Fluke 83. I can also see the voltage with my computer through the OBDII connector. Yes the voltage is way high. When I checked the old sensor on the bench with the torch it read .5 volts.

CEL P1133 The front O2 sensor on the 99 Impreza I picked up is steady at 3.8 volts. I put in a new sensor and got the same results. All the wiring seems to check out. Blocked CAT???? It runs fine, just made a 2000 mile trip. The CEL is for the front bank no response. Ideas? Thanks

Get the codes from the ECU. Is the CEL on? It could be anything!

I have 3 good used units. $40+shipping. Lmdew@hotmail.com

It's splined on both ends so unless you took it off your steering should be OK. If you pulled it, the steering wheel may be off center but no alignment problems. Tight is good, I've never seen one back off.

I have a good set of senders and a pump, your's for $40+shipping from CO. Lmdew@hotmail.com

If the trans drive spins without moving the car, the gear is trash. You can not pull the shaft up, as it has a c-clip on the bottom. You will need to pull the passenger side axle, the stub shaft, the bearing housing (make sure you mark it for proper bearing load) and then you can get in and change the gear/s. Not an easy job, I'd get a new outter seal and the oring for the bearing housing. Make sure you do not cross thread it when you put it back in.

The drive may have failed in the trans. Check to see if the output is turning as the car is dirven. Plastic gears in some trans.

The dealer is trying to work things out. The Ebay Manager, Jason was goint to drop the car for me at MHT, but then the owner put the brakes on that Idea. Now I have to wait overnight, 12 hours of drive time lost. The dealer closes at 6 and I do not land until 6:45pm From NASIOC I have a possible ride and links to local transport so I can get to the dealer. Then its just the 2000 mile trip home. Lifes a trip, enjoy the time you have :>) Thanks to All, Larry

I'm flying into MHT on Friday evening. I have to get down to Subaru of Nashau, NH. Other than taking a taxi, I have not found public transportation. Anyone close by? I'm picking up a 99 Impreza to drive back to Colorado. Thanks, Larry Lmdew@hotmail.com

I think the temp sensor and fan switch are different. Look at the R/H intake manifold. You should see two sensors. You can put the ECM into D-check green connectors if my memory is correct and the fans should cycle. If they are doing that the wires should be good. Have you burpped the system? If there is air in the system it will cause problems. Good luck. Larry

Back off the tie rod jam nut. Remove the tie rod (TR) cotter pin and nut. Unscrew the TR end. Count the threads or measure so you can reset the toe. Remove the outter boot clamp. Slide the complete boot off. Clean the rack end as much as possible. Reverse order and your done.
