I have a 2002 S-10 Zr-2 4.3 6cyl. vortec. Check engine light is on. Simple analysis indicates an O2 sensor. I am aware of the 2 sensors on either side of the catalytic converter. Are there more?

Not so great with automotive anything so started with you guys.

What do code p1131 mean on a Lincoln Continental 2002


Lack of Upstream Heated Oxygen Sensor Switch Sensor Indicates Lean Bank 1
In simple terms, it means the engine computer is not "seeing" the O2 sensor switch from rich to lean like it should be doing.
When the O2 sensor switches to lean the computer makes the injectors open more to let in more fuel, until the sensor switches to rich.

2003 chevy aveo #1 O2 sensor


#1 is the up-stream sensor (The O2 sensor located before the Catalytic Convertor). #2 is the down-stream O2 sensor. This sensor is located after the Catalytic Convertor. I hope this helps, let me know if you have other questions concerning this issue. Good luck.

How many oxygen sensors are there on a 1996 ford explorer 8 cyl., 4.0 eng.


The answer depends on the type of exhaust system you have. You will have either 3 or 4 total O2 sensors on your V8. If you have single exhaust with a single catalytic converter then you will have 3 O2 sensors (2 upstream sensors & one downstream sensor - "up or down stream" meaning before of after the catalytic converter). If you have either dual exhaust and/or two catalytic converters then you have 4 O2 sensors (2 upstream & 2 downstream). If you have an MIL light (malfunction indicator light, or "check engine light") the code will indicate "front bank / bank one", which is one of the 2 upstream O2's before the catalytic converter(s), or "rear bank / bank two", which is one of the O2's after the catalytic converter(s).

1998 gmc Sierra Engine light comes on and says O2 sensors. Replaced all sensors. Next day the light comes back on and says O2 sensors. What causes them to blow?


Hi, there are a number of trouble codes associated with the O2 sensors. Some indicate a sensor failure and others indicate a different problem. Can you tell me the trouble code you are getting?

During inspection I found out that a o2 sensor was bad but i was reading up on them and aparently there are four o2 sensors. 2 upper and 2 lower. How am i suppose to know what one is bad? secondly my...


The check engine light is blinking usually because of a misfire which can cause damage to the cat. The blinking check engine light does not necessarily mean the the cat is damaged.

The first thing you need to do is find out what codes are causing the check engine light to come on. If there is an O2 code it will help you identify the O2 sensor. The sensors are divided into to banks. Bank one is the same side of the motor as the number one cylinder. Bank 2 is the other side of the motor. Then they are divided into sensor 1 and senor 2. Sensor 1 is always before the cat. Sensor 2 is always after the cat. So if you had an O2 code for the Bank 2 sensor 1 O2 sensor it would be the opposite side of the engine from the number one cylinder and the sensor before the cat.

IMO, your first priority should be to figure out why the engine is misfiring and causing the check engine light to blink. Solving that first may take care of the O2 issues or the O2 could be the issue.

Replaced bank 1 sensor 1 O2 sensor with an OE


Those lights indicate an issue with ABS or traction control systems. In order to properly diagnose the problem the vehicle's codes will need to be read with a scanner.

Generally speaking there is no danger in driving the vehicle but be aware you may not have functioning traction control and/or ABS while those lights are present.

Check engine light on for sometime. Analysis said O2 sensor? Car just stopped in middle of road and lost gear. Would not drive or engage in any gear to include reverse??


SOUND LIKE TRANSMISSION RANGE SENSOR BAD.NOW MAKE SURE YOU HAVE BATTERY POWER.TRANSMISSION WONT ENGAGE IF BATTERY DEAD DUE TO BAD ALTERNATOR.

I have a P0171 to lean bank 1 error code Upstream O2 sensor?


oxygen sensor, vacuum leak, and yes it could most definitly be if you swaped the wires of the firing order accidently you will get a code p0171 Check the tubing going from the air filter to the intake manifold to see if it has come loose. This might account for extra air going into the intake manifold than the computer is aware of. Otherwise it may be due to a faulty(or dirty) MAP/MAF sensor. Another possible cause is from low fuel pressure due to restricted fuel lines or a bad fuel pump.

(o2 sensor indicator light cancel switch.) I need to fix this. I changed my o2 sensor and the light hasn't gone off, and it runs the same weather or not the sensor is pluged in or not.


could have wiring damaged need to check if signal from O2 sensor is getting to engine ECU.
can see this in data display using tech2 or scanner O2 sensor reading would be around 450mv all the time indicating open circuit(this is a default reading used by ECU)
or with multi meter back probe ECU connector O2 signal wire to see what reading if any getting to ECU.

2002 Alero check Engine light Codes P0132, P0137


Code P0132 is O2 sensor voltage high bank1 sensor 1, P0137 is O2 sensor voltage low bank 1 sensor 2, P1189 indicates a fuel control problem bank 1. It could be either the O2 sensors or a convertor. Could also be intake manifold gaskets. GM had a lot of problems with the lower intake gaskets leaking on the 3.1 and 3.4 engines that was linked to their Dexcool coolant. In fact they just lost a class action lawsuit about it. check with the dealer and see if the intake problem has been taken care of. Hope this helps.
