Question about 1997 Dodge Neon

1 Answer

Engine burning leam.

I have replaced both oxygen sensors up stream and down stream sensors,this cleared that error code.
Now the service engine light is back on with a new problem,bank 1 said the engine is burning lean.I don't have the error code,I am geting the worst mileage from a 2.0 dohc 4 banger engine.
P.S. I had the heads rebuilt installed new timing belts and gaskets I have no compression leaks.But I do need to replace the automatic 3 speed transmission.
Thank You

Replace the egr valve unit.make sure u do not have a vacuum leak in the line that lead in and out of the EGR unit.the egr controls how much fuel to dump into the injectors depending on the vacuum pressure in its system.sometime to much fuel sometimes to little fuel.

Now here's the weird part I had the o2 sensor changed ( down stream) the check engine light was cleared but it keeps popping back on saying that the heater circuit is low.....P0037 is the code


The folks that worked on it, have to continue on
& work on the heater circuit wiring

You don't need to clear any codes or check light
It will go off when the Oxygen Sensor Monitor runs

In your case, you still have not found the problem
The old sensor may have been good

1996 Toyota 4runner 3.4L error code p0133


SAE J2012 Revised DEC2007 lists Diagnostic Test Code (DTC) P0133 as "O2 Sensor Circuit Slow Response Bank 1 Sensor 1"

This code basically means that the upstream oxygen sensor on bank one of your engine is not responding as quickly as it should to changes in oxygen leavels in the exhaust.

The usual causes of this is an oxygen sensor that is just plain worn out (if it has a lot of miles on it) or an oxygen sensor that is contaminated by engine oil or antifreeze leaks causing these fluids to be burned in the exhaust (like bad piston rings, defective PCV valve, blown head gasket, etc.).

In any case, the oxygen sensor needs to be replaced. However it should be noted that if it is caused by contamination like that described above, replacing it will only result in a new oxygen sensor doing the same thing if the cause of the contamination is not repaired.

Hello! My long time (recently not so helpful) mechanic told me my engine light was on due to an O2 sensor code. This lasted at least a year and now the car is giving a code for the Cat Converter. Do you...


replace the o2 sensor,, clear the codes ,, and see if that cat code comes back, they work in unison,, so you may just need the O2 sensor, and all codes will clear

O2 sensor is comming up on service engine light warning, auto parts store says that there are 2 sensors on the car. Up stream and down stream. What are the locations for these and how hard are they to...


Hi Steve ..it refers to the location of the oxygen (o2) sensors relative to the engine. The upstream sensor is the one closest to the engine. The downstream sensor is furthest from the engine. Think of it as the way a stream of water, or in this case, a stream of exhaust flows.... From the engine To the tailpipe.
Changing them is no problem, getting to them sometimes can be a bear,, if you can reach them,, its simply remove the old one with a couple of bolts, and unplug it,, and replace

Check engine light was on. Connected scan tool, got data below and cleared faults. drove car 5 miles, check engine stayed off. p0300 random multiple misfire detected p0325 knock sensor 1 circuit...


If the check engine light stayed off then that means that those errors are not present at this time. It is not un common to have intermittent faults but I would not preced any further until the light comes back on. Then re-scan the code see which are to begin diagnostics.

Check engine light on- auto zone scanner shows error code p0053 probable cause: 1.-check circuit fuse 2.-relay defective 3.-check circuit wiring Where are fuse and relay located?


The code P0053 is for your Bank 1 Oxygen Sensor, the closest Oxygen Sensor to the engine, connected to the Exhaust. Replace your Oxygen Sensor, clear the code, and see if it comes back.

Code p0171 system too lean bank 1


I could be wrong but that sounds like maybe an oxygen sensor (bank 1). Not sure what code i had on my car but the only bank 1 and bank 2 I heard of is the oxygen sensor but you can always go to autozone and they can check the code and tell you what it is.

Need to replace oxygen sensor


TO REPLACE OXYGEN YOU NEED A SLOTTED SOCKET AND A TUBE ANTI SEIZE COMPOUND. MOST OF THE TIME NEW OXYGEN SENSOR ALREADY HAS ANTI SEIZE COMPOUND USED ON THE THREADS.TO REPLACE OXYGEN SENSOR FIRST CRANK VECHICLE FOR A FEW MINUTES SO YOU CAN REMOVE OXYGEN SENSOR MORE EASILY. ONCE YOU GET THE EXHAUST LITTLE WARM.YOU DISCONNECT OXYGEN SENSOR CONNECTOR TAKE SLOTTED SOCKET REMOVE OXYGEN SENSOR APPLY ANTI SEIZE ON OXYGEN SENSOR THREADS THE SCREW IT IN PLACE..WEAR LONG SLEEVES COVERALLS, SAFETY GLASSES KEEP RUST PARTICLES GETTING INTO YOUR EYES. AND LEATHER GLOVES KEEP HANDS FROM CUTS AND EXHAUST BURNS. IF YOU REPLACING DOWN STREAM OXYGEN SENSOR YOU HAVE TO RAISE VECHICLE SUPPORT ON JACKSTANDS. FOR UP STREAM OXYGEN SENSOR YOU CAN REPLACE WITHOUT RAISING THE VECHICLE.REASON I SAY CRANK ENGINE TO WARM UP EXHAUST SYSTEM BECAUSE METAL EXPANDS WHEN HOT THAT MAKES REMOVING OXYGEN SENSOR EASIER. IF YOU DONT CRANK VECHICLE THE COLD CAUSES METAL TO SHRINK MAKING HARDER TO REMOVE OXYGEN SENSOR.POSSIBLY DAMAGING SENSOR THREADS WHILE TRYING TO LOOSEN SENSOR FROM EXHAUST MANIFOLD OR PIPE. YOU CAN BUY SLOTTED SOCKET AND ANTI SEIZE COMPOUND AT ANY AUTO PARTS STORES.

Check engine light is on


P0135 02 Sensor Heater Circuit Malfunction (Bank 1 Sensor 1)
P0136 02 Sensor Circuit Malfunction (Bank I Sensor 2)
check for a blown fuse, if it is blown replace it, if it blows again after engine is started you have either a shorted O2 sensor or the wiring leading to the up stream or down stream sensors.
