What was the code? did it end with a 1, that is downstream. Or 4, that is upstream

Hi DALE,HERE'S A LINK TO YOUR CODE AND POSSIBLE CAUSES,THE SENSOR IS BANK I,SENSOR,WHICH MEANS IT'S ON THE SIDE WITH CYLINDER I AND 2 SENSOR WHICH IS LOCATED BY CATALATIC CONVERTER,HERE'S A LINK TO YOUR FIRING ORDER.fIRST LOOK AT SENSOR AND WIRING TO SEE IF ANYTHING IS OUT OF PLACE,LOOSE WIRE OR DAMAGED SENSOR,ALWAYS USE EXACT FIT ONES,NO WIRE SPLICING.

If this is a digial gauge check fuses first. speed senser at the back of transmission 1 10 m bolt. auto zone maybe able to check the part. Stop by Auto Zone have them run free code test. code will for senser. If manual check cable on back drivers side of transmission.

Duplicate question.

P0031 Oxagen senser heater circuit. The heater circuit can be checked with a test light connected to ground. ( a tast light is an ice pick looking tool with a clear handle with a 12 volt bulb inside and a ware with a clip to connect to grond, the light will light as the tip is touched to anything powered up with 12 volts and sometimes a little more and a wholde lot less) Find the oxagen sensers ( thier screwed into the exhaust pipes) Disconnect the electrial connectors and connect the test light to ground, with the key on test the wires in the plug connect ed the vehical. one of them should light the light, if it does reconect it and test the rest of the sensers, recalling which wire was live. ( most are white or grey but they vary some. If all the sensers have power it's not the power but the senser failed. with an ohm meter test the senser for the wire that was hot to the other wire that is the same color if the sneser is open ( no circuit ) you have found the bad senser. If you can't find power going to any of the sensers. Check the fuse boxes for blown fuses ( check them all with a test light) If you find a blown fuse replace it but go back to the wiring tjat connects to the sensers and you'll find someplace where the wire melted to the exhaust pipes and shorted out, blowing the fuse. The sensers short out too but not very often.

did u change the right o2 sensor there is 2 sensors on bank1 and 2 on bank2.....upstream and down stream.....i had the same prob i changed the o2 senser to the other side to check and make sure it was the o2 senser....it took 4 o2 sensors before i got 1 that finally worked nd yes i was buying them brand new.....so change sides with it nd see if the code changes sides....and did u reset it with the code machine when u put the new 1 in?

lose connection at one of the sensers.Check the plugs under front seats and clean the termials.

Hi, check front hood micro switch at latch or radio switch for antitheft it is open.

Changing the O2 sensor for a P-0135? Use a TOYOTA sensor. The aftermarket/generic sensors do NOT work in Toyotas.

User with the smoking problem: Remove the valve cover & check for engine oil sludge where the cams ride. If it is sludged, a rebuild is necessary, BUT, Toyota DOES have warranty assistance for this issue. All you need are oil change receipts.

those are transmission codes vehicle specific that year beetle has numerous recalls
