P1133 HO2S Insufficient Switching Sensor 1

Does this code mean front O2 sensor is bad?
Is there anything else before I attempt to replace it? I cleared the code once but it came back.
Rear O2 sensor was replaced three months ago. Could there be something keep making my O2 sensors go bad? Or is it just about time to replace? My S70 T5 has 95,000 miles on it now.

Another question,
fcpgroton oem part number includes 15667. I found that cheaper on Amazon
But Amazon actually shows different part number for my Volvo, which is cheaper at other site.
Which one is correct one?

Now the code has changed to P1132.
Code reader freeze frame data shows the following info.
Fuel Sys 1 CL
Fuel Sys 2 NA
Calc Load (%) 2.7
ECT (F) 165
STFT B1 (%) -10.1
LTFT B1 (%) 12.5
Eng RPM 1280
Veh Speed (mph) 37

I also tighten the all the clamps on vacuum hose or air intake as many as I can. Tried spraying electronic contact cleaner (I don't have carb cleaner now) while idling, but didn't see any difference. I feel power slightly decreased but mileage seems the same. Idling is stable as always. When I get in the car after parked for a while, I smell some fume but not strong. not sure if it is exhaust smoke smell or fuel. more like in between. I don't see any colored smoke coming out of tail. I cleaned the MAF using MAF sensor cleaner. Fuel filter was replaced a month ago. Looked at the injectors and couldn't see anything leaking out around them.

 

On these cars the O2 sensors seem to go out in pairs, so you probably need the front sensor.

If you search this site, you'll find many who opted for non-OEM O2 sensors; they were always sorry.... Don't repeat their mistake..

BTW: Is this a '99 MY? Also appears they're slightly less at IPD.

 

Yes, mine is 99 S70 T5. I am not trying to get cheap non-OEM substitute but just trying to get OEM cheaper. It seems that IPD has better price, but after 10% coupon and free shipping, same as fcpgroton. Would still better if there is IPD coupon (is there?).

The volvo part number of the front O2 sensor of my 99 T5 is 9470983.
Assuming that Volvo uses Bosch sensors without customization, did some research on the cross reference part numbers.

According to the Bosch web catalog, the part numbers are

'99 S70 turbo (B5234T3, B5254T)
16197 OE Type Exact Fit Downstream or 4-wire heated
17038 OE Type Exact Fit Upstream or 5-wire wideband A/F
So, what I need is 17038 if this is correct information. I need to see if it matches with the volvo part 9470983.

'99 S70 non-turbo (B5254S)
15062 OE Type Exact Fit Downstream or 4-wire heated
15097 OE Type Exact Fit Upstream or 4-wire heated


'00 S70 turbo (B5234T3, B5244T)
16197 OE Type Exact Fit Downstream or 4-wire heated
17070 OE Type Exact Fit Upstream or 5-wire wideband A/F

'00 S70 non-turbo (B5244S)
15035 OE Type Exact Fit Downstream or 4-wire heated
15558 OE Type Exact Fit Upstream or 4-wire wideband A/F

'98 S70 turbo (B5234T3, B5254T)
15063 OE Type Exact Fit Downstream or 4-wire heated
15097 OE Type Exact Fit Upstream or 4-wire heated

'98 S70 non-turbo (B5254S)
15062 OE Type Exact Fit Downstream or 4-wire heated
15097 OE Type Exact Fit Upstream or 4-wire heated

There are also OE smartlink universal fit sensors, but I assume what I am looking for is the exact fit.

Looked at the IPD cross reference numbers, they all match except only one, front sensor for 99 turbo, which is what I am looking for. I checked fcpgroton, and their number does not match with any.

According to Denso oxygen sensor cross reference list, Bosch 17038 matches Denso 234-5702, and this matches volvo 9470983.
This is why I suspect that both of the IPD or fcpgroton numbers are incorrect. Otherwise, Volvo has changed the part design, in which case I should go with either IPD or fcp.
Another thing is that some web store sells o2 sensor cable, which might explains the dramatic price difference, but I don't know if I will get this together when I pay $150ish for the sensor.

Also, the life span must be close to 100,000 miles as they are to be checked or replaced at 100,000 miles interval. That may as well explain why they fail about the same time.

 

You've done a lot more research than i have...

I would call both IPD and FCP and ask why their numbers don't match the Bosch reference; probably a reasonable explanation. Tech might know too...

 

I googled the number on IPD, 0258007038, and found one site cross references it to 15667, which is the number fcpgroton lists. This number must be European reference number or something because I can find it on Bosch UK site. Also, a fcp guy confirm that 15667 is the correct one.
I just got one from amazon for $70 and its part number is (15667, 0258007240D09). So, it is not the same thing that IPD sells. One way to find out whether this is going to work or not.

 

The code has come back as P1132. I reset it a couple of times but it keeps coming back.

When I got the code first time after the O2 sensor replacement, my code reader had the following freeze frame data
Fuel Sys1 CL
Fuel Sys2 NA
Calc Load (%) 10.1
ECT (F) 163
STFT B1(%) 0
LTFT B1 (%) 17.9
Eng RPM 2200
Veh Speed (mph) 64

Second time data is as below
Fuel Sys1 CL
Fuel Sys2 NA
Calc Load (%) 11.3
ECT (F) 183
STFT B1(%) -4.6
LTFT B1 (%) 14.0
Eng RPM 2360
Veh Speed (mph) 68

Any advice?

 

Seriously doubt that is an OEM part for that price. Can't prove it but i bet there's a difference between "OEM" and "OE Type Fitment" when it comes to O2 sensors. Anyway, that's my guess...

 

My problem has been solved finally. It was the problem described in the service bulletin https://volvoforums.com/forum/volvo-v70-13/ets-check-engine-lights-553/
Mine actually falls into one of those affected chassis numbers.

So, I replaced front O2 sensor again with the one I got from IPD this time. It didn't do the trick. After reading that service bulletin, I got a front adapter cable from dealer and a rear adapter cable from IPD. It still didn't fixed the problem.
So, tried a simple experiment. I disconnected the rear O2 sensor cable, and the car ran fine though it set rear O2 sensor code. When I connected it again, the car start running rich after 50 miles and set the front O2 sensor code. So. I figured I should replace the rear O2 sensor, which was actually almost new and only 4 month old. After replacing the rear O2 sensor, the problem has gone. Since then, I haven't had the problem back for about a month now. So, I guess 4 month without an adapter cable is long enough to deteriorate the sensor with the silicone at the harness. I am happy than the problem is gone but now no money left to buy a new set of tires for the winter.

 

I purchased a Bosch 15097 O2 sensor listed as "Oxygen Sensor - OE Type - Exact Fit - Upstream Sensor 4" on Vehicle Part Finder

The new sensor has an in-line connector and the old one has a 'box' style connector. Why the difference? Since I got this on-line, it's not convenient to send it back for a replacement so I was wondering if I could just splice and solder the wires. The new sensor has black, gray and 2 whites. The old one has white,blue and 2 blacks. What splices to what?

Thanks in advance.

 

Here are pictures of the 2 different connectors.

 

Figured it out. The 2 blacks go to the 2 whites. The gray goes to blue and black to old white to the new black. Had to trace the wires the old fashioned way and heat up the sensors to determine polarities. The double wires go to the heaters.

Hope that helps anyone in the future.

Thank-you Andrei (friend I called).
