I changed both oxygen sensors yesterday on my 1997 Accord.
Check Engine Light was on and I was getting codes:
P0135 - O2 Sensor Heater Malfunction Bank 1 Sensor 1
P0141 - O2 Sensor Heater Malfunction Bank 1 Sensor 2
Also, after clearing the codes, if I started the vehicle the codes would come on instantly. So it wasn't some kind of flaky electrical issue, it was consistent.
I have a 2005 Impala with the 3.4 engine and 118,000 miles. About 2 years ago I had a code P0141 and since we didn't know for sure which oxygen sensor was out we replaced both of them. The P0141 code did not stop occurring after both sensors were changed. I read on an Impala forum that if you didn't replace the sensors with AC Delco the codes would continue so I didn't worry about it until my gas mileage starting going down recently. I ordered new AC Delco oxygen sensors and my husband replaced them Saturday, the old ones were sooted up pretty badly. Today a new code appeared, it is P0140, O2 sensor circuit no activity. What the problem might be now.
View 7 RepliesMy son-in-law has a 2006 Honda Accord with over 160,000 miles on it. About 8 months ago, the check engine light came on. The code said the down stream oxygen sensor was bad. He took it to a Honda dealer and they replaced the sensor and now the check engine light is back on with the same code. Can the catalytic converter have gone bad and can it have made the oxygen sensor go bad too?
View 5 RepliesLooking for a diagram of the locations of the oxygen sensors on this vehicle, I am getting miss information from all around saying it has anywhere from 2-4 oxygen sensors and i think it has 3 am i right? two in the front behind the radiator on the exhaust manifold, and 1 somewhere by the catyaltic converter. There isn't a whole lot of manuals out there for these cars.4.0 ltr engine...
View 4 Replies1997 2wd, 4.0 - As you can guess it runs pretty bad at idle. It has O2 heater circuit codes for all 3 sensors. I'm leaning towards the ECM because the 2 heater wires are both hot with the key on. I unplugged the computer and turned the key on and just one wire is hot. Looks like the ecm is supposed to ground the wire to turn the heater on, but it's going hot instead?
View 14 RepliesMy 2002 Dodge Dakota Extended Cab pickup is throwing several different 02 sensor codes. The first one was P0132. I reset the CEL and it ran good for about 1800 miles (100,140) on the odometer now. Now I'm getting a P0158 code and CEL went off after a few miles. Now it's back to a P0135 and P0138 code. Are the 02 sensors really bad or is there an underlying problem with the wiring or the computer. The truck runs like new when the CEL is off. The P0132 has never shown up again. The engine is the 3.9 V6 and is 2WD.

View 1 RepliesI've been looking online to see how often you need to replace the oxygen sensor for the 3rd gen Prius. I can't find anything online. How often you replace these? Would it be around 100,000 miles or more because it's a hybrid? Also how many are there? I've heard there is 2 and some say there's 4.
View 2 RepliesI drive a 2001 Toyota Camry with about 110,000 miles. About a year ago the check engine light came on and indicated a problem with the rear O2 sensor (the exact OBD code escapes me right now). Had the sensor replaced and a month later the same one failed. Replaced it again and 2 weeks later it failed again. I am now on the fourth rear O2 sensor and the check engine light is on again with the same code. So, clearly the problem isn't the actual sensor. I have heard it might be the ECU, but what else could be causing this type of problem?
View 4 RepliesI am having problems with a 2003 Ford F 150 with a 4.2 L V6. The problem is that it is giving me code errors that would indicate bad O2 sensors. I replaced both the upper and lower O2 sensors, and still I get the same codes. I was told by the mechanic with the computer reader that this usually means a bad vacuum seal. He suggested looking for bad hoses, but did not offer much more than that. How to proceed?
View 2 RepliesI just checked my computer I have a couple codes
P0453 evap emission system pressure sensor/ switch high
P0232 fuel pump secondary circuit high
C1303 right front isolation clamping circuit..
P0305 cylinder 5 misfire.
I changed the fuel pump 2 days ago and the coil on cyl 5.
Still getting p0174 error after upsteam downstream, checked everything.
View 1 RepliesI've changed the upper and lower O2 sensors the Manifold/Cat and still getting the code. Was wondering if the the valve guide seals would give off this code.
View 3 RepliesI recently had my Hyundai Entourage (2008) come up with the following engine codes: P0057 and P0037, both related to the downstream oxygen sensors. The generic description of the code is heated oxygen sensor heater control circuit low. As I understand this code, it is signaling that there is too much current passing through the heater circuit. The oxygen sensors test out OK for resistance, around 10 Ohms each and disconnecting them entirely and rerunning the test after driving a few times yields the same code. So I suspect the issue is not with the sensors but either the wiring or the ECU. I'd be a little surprised at a sudden short in the wires for both sensors but I suppose stranger things have happened. Oh and the fuse for the oxygen sensors has not blown. I am correct in reading these codes to mean there is an apparent short? Or are there any other things that could cause this to happen?
View 3 RepliesWhat can be done regarding these faults? P0037 and P0057
Description:
Oxygen Sensor Heater Control Circuit Low (Bank 1, Sensor 2)
Oxygen Sensor Heater Control Circuit Low (Bank 2, Sensor 2)
The catalytic converters have been removed but the fault was present before that anyway. All I want is the VSC function to work again and the lights to go off. I have heard you can put dummy sensors in.
Long time follower, first time user. 99 F250 V10 180,000 miles: About a month ago I replaced both upstream oxygen sensors. I know have the following codes:
0135 and 0155 for Upstream Heated Oxygen Sensor Heater HTR 21 and 11
Circuit Malfunction Bank 1 and 2
1409 for Exhaust Gas Recirculation Vacuum Regulator Solenoid Circuit
I checked fuses and PCM relay and all are good. I have 12 volts to both oxygen sensors and no noticeable wire burns. One of the possible causes given on code printout for 0135/0155 is to check for a disconnected hose to the EGR. All hoses are good. One of the possible reported fixes for EGR code 1409 is to repair oxygen sensor wiring. So my question is: Are these codes related. If I replace the EGR vacuum regulator solenoid, will this clear my codes from the oxygen sensors?
I have a 2000 motorhome on a f450 chasis. It has a V-10 with only two oxygen sensors up-stream from the catalytic converter. The monitors for the oxygen and oxygen heater sensors will not show "ready". I replaced both sensors and have driven it over 200 miles. They still show "not ready".
View 5 RepliesThis isnt my first vw but its my first vr6, its a 2000 gti glx, only showing codes for o2 sensors havent got a vag com yet only have a obd scanner. It idles fine and runs smooth until i get over quarter throttle then it starts hesitating like there isnt enough fuel or air...i know that the noob owner i bought it from cheaply put exhaust on it and i didnt see any o2 sensors but ive never known a car to not run correctly without them.

View 10 RepliesI have a 2002 Honda Accord SE with 228K miles. Leaking oil (oil spots on garage floor). My mechanic, where I get my oil change, said it looks like it is leaking oil and transmission fluid- he referred me to a reputable auto repair shop. The auto repair shop put some kind of dye in my car and told be to bring it back after driving 50 miles. Two days later I took my car back. They said I was not leaking transmission fluid but oil. They said my valve gasket, and my cam, crank, and balance shaft seals are bad.
They replaced the gasket and seals. I also had them to replace my timing belt and water pump since it was last changed at 113K miles. I continued to find fresh oil spots on my garage floor. I returned to the auto repair shop. They inspected my car and said I need to replace the VTEC gasket. I had them to replace the VTEC gasket. A few days later, I noticed some more oil drops on my garage floor. I returned to the auto repair shop and told them to keep it until they discover where the leak is coming from. My car is currently at the auto repair shop two days later. Do you think this oil leak problem mean that the end of my car is near? Is it worth repairing?
Where the fuse that controls oxygen sensors on a 1997 pontiac grand prix 3.8L engine? i read some where it is under hood fuse panel, but what is the marking for the fuse?
