1999 Volvo S70 P1057, P0722, P0717

We bought a Volvo S70 for my daughter. Stupidly, I did not run it by AutoZone...no check engine light was on. I discovered the bulbs had been removed. So, of course, it will not pass emissions.

Orginally the OBDII scanner from AutoZone showed four (4) codes, in this order:

-P1057 (?)
-P0137 (O2 circuit low, bank 1, sensor 2)
-P0722 (Output shaft speed sensor circuit no signal.)
-P1057 (?)

Here is what I have done:

-Corrected O2 sensor. (No more codes now.)
-Cleaned ETM thoroughly. (Quite a few posts saying this causes issues.)
-Replaced spark plugs
-Cleaned Vacuum hoses. (Some little ones were quite plugged.)
-Visually inspected ABS module internals. (Many, many posts about this. Mine had zero solder connection issues.)

After doing all this, I decided to take the silly thing to Volvo, pay $90, and have them diagnose the problem. At this point, and after many hours of research, I half suspected the Vehicle Speed Sensor, so-called. But I wanted to be sure.

Volvo found these four issues:

-"Customer states check engine light is on. Check and advise needs Vehicle Speed Sensor."
-"Column lock faulty."
-"Right Axle boot faulty."
-"Power steering pump leaking."

"Great," I thought, "all I need to do is put in the Vehicle Speed Sensor, and I'm good."

I installed it.

Now I have the following codes:

-P1057 (?)
-P0722 (Output shaft speed sensor circuit no signal.)
-p0717 (Input turbine sensor curcuit no signal.)

The car drives fine. The transmission shifts fine, and does not slip, or jump into/out of gear.

The "Service Engine" light comes on when the car is started, then goes off about a minute later.
The "Check Engine" light comes on and stays on.
The "Flashing Arrow" light comes on and flashes.
The "SRS" light comes on and stays on. (Not sure why Volvo had no information about this for me.)

And so, in conclusion, I am at my wit's end. I am not sure what to do, or if anything can be done. If anyone was willing to help me get this solved, I'd be eternally grateful. (Even if all I am able to do is pass emissions, I'd be satisfied.) And I'd be more than happy to give advice on plumbing, which is my strength, if needed.

Thanks.

Does your ETS light come on when you turn on the key? It's important you know if the electronic throttle system has any errors because that may be enough cost to reconsider this whole deal.

Someone went to a lot of trouble to remove that CEL ..is it gone or burned out?

People who do this to cover up a car problem should be shot on sight. If I bought a car and found it removed........

Good news..service light is just a reminder and has no diagnostic value or indicator of a problem.

Thank you for the quick reply!

I'm not sure if the ETS (Electronic Throttle System??) light comes on. I will check when I get back to the house, and post a reply then.

No, the bulbs were NOT burned out. They were removed. The "SRS," "Flashing Arrow light," CEL, and Service engine bulbs were all REMOVED. Like I said, I really should have thought about looking for that...

Ok. ETS light comes on when you start the car, and a few seconds later goes off. I'm guessing that, at least, is proper.

Ok..I did a little poking around because I'm waiting for a flight.

P1057 is a tricky one to find, but it might just be a Volvo code for the Transmission control unit (TCU) telling the ECU to turn on the CEL....unconfirmed.

The rest are all indicative of the lack of signals from the two sensors. Once the car isn't talking to the transmission, it isn't happy because it needs these things to tell the transmission what gear to be in.

I'm betting you have some dirty connections on those sensors, and taking the wire harness off them and cleaning might help this whole thing get back to nirvana.

Volvo should have told you what the SRS code is...that one has to be cleared by the dealer. If some had either airbag disconnected or a front seat removed and powered on the ignition, that will trip the SRS. You can pass inspection with SRS on in my state.

The person who removed the lights from your car just had a sewer line back up into their basement, btw. Karma is a female dog,

I will purchase some cleaner, and clean the contacts tomorrow.

I sincerely appreciate the help!

Ok.

So I cleaned every sensor power clip I could find with electronics cleaner from Autozone. After re-assembly, the CEL was still on. (As was the SRS, Flashing arrow, and SEL, of course.).

I thought, 'what the heck, I'll re-install the original speed sensor and go check the OBDII codes. It gave five this time, instead of three. They were P1057 (x2), P0722, and two which numbers I neglected to write down, but which were "Input speed sensor" and "output speed sensor" respectively. (One was still the P0717, I believe.)

My current plan is to contact a salvage yard Monday and purchase the two Turbine sensors; then replace them. After which, I will see what codes--if any--are being given.

I did forget to mention that the car has a NON-turbo, 2.4L engine.

Thank y'all so very much for the help.

*Turbine input/output speed sensor respectively...

Update:

(Any ideas, suggestions, etc., would be GREATLY, ABUNDANTLY, EMINENTLY, and INFINITELY, appreciated.)

I have changed the VSS, and the Engine Speed Sensor. (Volvo dealer said to.)
I checked supply voltage at the VSS and have 7.4+/-.
I checked supply voltage at both Wheel Speed Sensors and had 12.5+/-.
I have thoroughly cleaned every sensor plug with Electronics cleaner.
I have attached a ground wire which I found to be disconnected.
I have cleaned and reattached about half of the ground wires I could find.

But, I am down to ONLY two codes: P0717, and P0715. (Input/output turbine speed sensor.) Surely someone knows of something I could check? I only have the Flashing Arrow and CEL.

The transmission operates properly through all gears.
The engine operates perfectly fine.
The instrument cluster works perfectly.
The ABS module had no bad solder joints, and the ABS light does not light up.

I am planning on ordering this part: http://www.miparts.com/oem/9496420. But I don't know if a wheel speed sensor has anything at all to do with my problem.

If that fails, I am planning on replacing these parts (driver and passenger sides): https://www.amazon.com/SurTrack-VO-8017- ... B00DCO599I . The reason being that the passenger side has a busted boot, and every great once in a while makes a "clunk" noise.

Irrespective of these planned activites, I intend to clean or replace the PNP switch, per this video: https://www.youtube.com/watch?v=mCyu_nJFA3I.
I also intend to check supply voltage at Engine Speed Sensor.

Thank you again for any help supplied.

Update:

I have flushed the transmission fluid per the instructions here: https://www.matthewsvolvosite.com/forums ... f=1&t=8767

I have changed the oil and filter.

Now, lucky me, I have four codes.

P1057
P0717
P0715
P1057

I have not yet changed the other parts I listed in my previous update.

I also have a difficult time believing that no one has ANY idea what I could do next. Of course, I realize this is a free forum, and that we all have very busy lives. So I am extraordinarily thankful for the help I have already received, and for any help that may come forth in the future.

But right now I am LOSING MY MIND trying to clear these damnable codes!

Updates to follow as I perform different things.

Thanks again.
