The ECU was the first thing I tried, a used one. The readings were the same. Not positive, but with two doing the same thing, I'm happy to make the leap and say that is what the system is looking for. If someone had a same make and model that would be a nice check. I read it out with my OBDII reader and the Fluke 87. There you go.

Nope, it stays up around 3.8 volts, with the normal up and down spikes for an O2 sensor, so 2.8 - 4.5 which is way high. I guess that's the way this car is set, as the ECU is happy.

Well, I got a Subaru front O2 Sensor and put it in. It still reads 3.8 volts, but now responds as it should instead of a constant 3.8 volts. I have never seen an O2 sensor with that voltage signal, but the ECU is happy and has been for the last week. I guess you need to get the SUBARU O2 sensors for proper operation. In this case the bench check did not help.

I can send you a good used one $25+shipping. Lmdew@hotmail.com Shipping from Colorado 80916. I can use my FedEx discount and it will be there in a few days. Later, Larry

They will swap right over. Leave it all connected so you do not have to recharge the system. You may have to use the 2.5 bracket and tensioner assy but it will work on your new 2.2. I've done 5 or so of these swaps and never had had a problem with the AC. Larry

I have an Subaru Alt, $25 shipped to a business address, add 5 to your house. Lmdew@hotmail.com

That's my guess as well. My 1.8 had the connector on the PS pump, but all the Legacy 2.2 that I have worked on do not.

Yep

You need to fish all the ECU wires out. Sometimes I pull the dash. Do they have a A-frame for the hoist?

Pull the gauge cluster and remove the speedo mounting screws one at a time, clean the contact area then put the screw back in. The mounting screws are the contacts for this speedo. If that does not do it, it could be the Speed sensor or if needed I do have a complete gauge cluster with a good speedo.

Did you try putting the fuse in the FWD holder, right front strut tower (auto trans)? If the FWD light comes on, on the dash you know the coil is getting power. Trans Flush, would be next.

Please let us know if it fixes the P1133 ECU code.

They sell special sockets for the Sensor Removal, but I've always used a 7/8 tubing wrench. Sears has them.

I'd check for power at the fan. If its there, the fan is bad.

Since the O2 circuit to the ECU is just getting input voltage from the sensor, wouldn't you think if the sensor was disconnected the wiring should be reading 0 volts? How do you check the internal circuits? Thanks for the info.

If they are good, those are reasonable prices. Used Trans are $750 or so from the yards, same for engines. You may want to drop a 2.2 engine in or watch for a wreck that has a good engine and trans. You may be able to pick the complete car up for less than a $1000.00 In the end, look at the life you will get out of the car.

HELP! Update: 1) I tried a used ECU and had the same results. 3.8 volts as seen by the OBDII readout. 2) I did resistance checks on the O2 sensor wires: - jumpped in the engine compartment (sensor-ground wire) 0.00 ohms at the ECU connector. - Individual wires to ground, OL (open line) With the ECU Connector plugged in and the key on: - Sensor wires 3.8 volts at the ECU and the engine bay connector (O2 sensor disconnected) - Heater wires 12.8 volts = battery voltage As I see it, the 3.8 volts is coming from the ECU. So either I have two bad ECU's or I'm over looking something. If you have the factory manuals with good wire diagrams on the ECU/O2 circuit please send them my way. Anyone with a 99 Impreza in Colorado Springs, I could hook my OBDII reader up to and check your O2 sensor voltage? Thanks, Larry

If the field plug is the same, it will work. I've done lots of 2.5 to 2.2 swaps and they all work as long as the plug is the same.

You could check another Subi and see where the piston is or put some sort of a spacer in between the clutch fork and the piston rod. That would force it in and you could see if you are getting full throw of the fork. Sounds like you may be in for a new clutch.

If you need a dash or other parts, call me. I'm in the springs, Larry 268-9750.

Watch Ebay or the message board. The come up often.

I just picked up a 99 same config as the one your looking at 130K for 3500. It needed struts and some other stuff. Check the craigslist in SFO or LAX.

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
