Question about 1998 Volvo S70

Open Question

Check engine sign on (codes P0133, PO140; PO410)

Volvo S 70, 1998 (Vin # YV1LS5643W2421782; 2.4 L, 117000 miles) has always indicted Check Engine sign on /off (since I brought it, in 2000) but passed the emission test for 9 years in MD and VA. (Even dealer did not do anything to fix this problem when the car was under warranty in 2000).

This year, VA MVA utilized OBDII in emissions testing and car failed for check engine signs (codes P0133, PO140; PO410). I wanted to keep this car for 1-2 years and now cannot afford to fix this electronic defect (in another wise healthy car).

Can you provide the location (sketch) of oxygen sensors on this car so that my friend could replace these two oxygen sensors?

OBDII in emissions testing is a greatest blessing for the mechanics and auto dealers? God bless America!

codes P0133, PO140; PO410: what is the reasonable cost to fix this problem? And how? There is dearth of honest mechanics/auto shops in this DC metropolitan area.

What are codes P0133 & P1134, for a 2005 Buick Lacrosse 3.8L V6 with 94,000 miles.


i have replaced an O2 sensor and had similar failure after 1500 miles.
I removed it, chkd it, reinstalled it and it ran fine.
P0133 is related to slow response of O2 sensor. P1134 is mfg specific so google that for ur car.

I have a 2004 corrollacode p0133 do you have fix for it


P0133 is code for aged O2 sensor(s) 120,000 miles or higher.

Is there engine blowing white smoke (losing coolant) or burning oil?

Any thing beside exhaust will shorten the life spend of the O2.

Change the one between engine block and catalytic converter first.

Front oxygen sensor code. Check the vacuum line to the fuel pressure regulator and make sure it is ok before you replace the sensor. Any vacuum leak can also cause the code.

03 s60 engine code p0133,replacet everything


P0133 - Oxygen Sensor Circuit Slow Response (Bank1, Sensor1)
This involves the front oxygen sensor on Bank 1. This code indicates the engine air fuel ratio is not being adjusted by the oxygen sensor signal or the ECM as expected to do so, or not adjusted as often as expected to do so once the engine is warmed or under normal engine use.

You will likely not notice any drivability problems, although there may be symptoms.

A code P0133 may mean that one or more of the following has happened:
The oxygen sensor is faulty
The wiring to the sensor is broken / frayed
There is an exhaust leak

Possible Solutions:
The simplest thing to do is to reset the code and see if it comes back.

If the code comes back, the problem is more than likely the front Bank 1 oxygen sensor. You will likely wind up replacing it but you should also consider these possible solutions:
Check and fix any exhaust leaks
Check for wiring problems (shorted, frayed wires)
Check the frequency and amplitude of the oxygen sensor (advanced)
Check for a deteriorating / contaminated oxygen sensor, replace if necessary
Check for inlet air leaks
Check the MAF sensor for proper operation

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

Code p0133


po 133 means front oxygen sensor signal is faulty, replace the front oxygen sensor that will solve your problem,you will have to reset computer monitoring system, may have to have a garage do this unless you have a scan tool, or replace sensor and drive with the check engine light on, while driving computer is always testing system, when it sees sensor working good it will shut light off. this will save you $$, but it may take a few days of driving,hope this helps.

P0401. P0133, P1131- emmision test


Based on what the tech manuals say I would change the DPFE sensor for the EGR Valve, careful not to tear the special silicone rubber hoses that go to it from the exhaust, as a Ford dealer tech I saw these codes allot, and the DPFE sensor was almost always the issue or the hoses going to it.
