Question about 2001 Oldsmobile Alero

2002 Alero check Engine light Codes P0132, P0137

Light has been on for about 2 years, Replaced both O2 sensors twice. Catalitic converter and Muffler twice. Most of the driving is highway driving. if prolonged city driving the light will go out for a while, how ever it appears that the gas milage goes down. I am at looking for solutions. my mechanic says that every thing checks out while idling in the shop and the codes indicate it is the O2 sensor or the catalitic converter. It appears that he want to keep replacing parts until we get the right one

    the the last few times I have had the codes read the following codes have shown up P1189 , P0132, P0137. the one shown most often has been P0132

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.

the code P0137 is low voltage o2 sensor bank 1 sensor 2.. mean o2 sensor rear of catalyst converter has low voltage it should stay around .500mv mean converter cat.do is job.with a voltmeter test backprobe signal when engine running. by default key on engine stop around .500mv.

Where is the oxygen sensor bank 1 sensor 1?


From the 2002 Oldsmobile Alero manual:
A device found in the exhaust manifold, which generates a small voltage dependent on the amount of oxygen present in the exhaust stream, used as a signal to the engine-control computer to determine the amount of fuel necessary to maintain a proper air/fuel ratio.
What this means to me is search the exhaust manifold for it - its screwed into it.
Unscrew it with a specialty oxygen sensor socket (a slotted 7/8-in hex socket) - available for
$10 at any parts store. This is likely the HO2S (heated oxygen sensor) Bank 1 Sensor 1, since
it is before the catalytic converter, the second oxygen sensor (Bank 1, Sensor 2) should
be the one located after the catalytic converter.

codes:
P0130 - HO2S-11 (Bank 1 Sensor 1) Circuit Closed Loop Performance
P0131 - HO2S-11 (Bank 1 Sensor 1) Circuit Low Input
P0132 - HO2S-11 (Bank 1 Sensor 1) Circuit High Input
P0133 - HO2S-11 (Bank 1 Sensor 1) Insufficient Activity
P0135 - HO2S-11 (Bank 1 Sensor 1) Heater Circuit Malfunction

Note the P0131 can be also be caused by a bad MAP (Manifold Absolute Pressure) sensor,
so yank the MAP sensor and check the computer for a lean fuel condition (P0131=low input).

I have a 2002 Chevy Impala 3.4L . I have had a check engine light and checked the codes , twice indicating a #2 oxygen sensor failure . I was told the car is operating in a closed loop mode , I have driven...


Hello! The #2 Oxygen Sensor is located "downstream" which means after the catalytic converter...The sensor is threaded and screws into the exhaust pipe to the rear of the converter...Downstream O2 Sensors are used to monitor catalyst efficiency while Upstream O2 Sensors have a pronounced effect on performance...Hence, engine runs fine...Problem is the vehicle will not pass inspection with a Check Engine Light on...The problem may be a bad ground, a contaminated sensor or a defective sensor...
Do you have a multimeter and a little experience using one? If not have the sensor replaced...If so, here is a procedure to check the vehicle's grounds...Set meter to X10 ohm scale...Place one probe on the center of the - battery post...The other on bare metal of the exhaust pipe...You'll need a long piece of 10Ga. wire...Reading must be zero or very close to it...If not, the O2 sensor is probably good and a ground strap needs to be installed...O2 Sensor pictured below...Cost is around $60 for the sensor and .5 hours labor...Guru.....saailer

Check engin light on. There are four error codes P0137,P0141,P0342, and P1792. How do I fix it. Will I pass inspection with these codes?


P0137 Error code Faulty O2 sensor Exhaust leak near the rear sensor
  • Plugged catalyst
  • Short to voltage on O2 signal circuit
  • High resistance or open on O2 signal circuit
Possible Solutions
  • Replace faulty sensor
  • Repair exhaust leak near the rear sensor
  • Check for restriction in catalyst and replace as necessary
  • Repair short, open, or high resistance on o2 signal circuit
P0141 Error code means Downstr Heated Oxygen Sensor Heater circuit fault - Bank No. 1.

- replacement is needed for this issue.

P0342 Error code means Camshaft Position Sensor Circuit Low Input

P1792 Error code means P1792 means the computer isnt properly programmed so if this code keeps comming back the pcm may need to be replaced

I just get a 2000 lanos but the check engine ligth is ON when i put it the code reader says to me 2 codes : 1st code is P0137 and p1336 say a lot lf items but got to be only one of those , whath can be???...


Essentially the same as P0136, P0137 refers to the second oxygen sensor on Bank 1. P0137 means the O2 oxygen sensor's voltage remained low for longer than 2 minutes. This, is interpreted by the ECM as a low voltage condition and sets the MIL. Bank 1 Sensor 2 is located to the rear of the catalytic converter and should produce an output signal relative to oxygen storage capacity of the catalytic converter. This rear (sensor 2) sensor is less active than the signal produced by the front sensor. However, if the ECM senses the sensor is inactive, this code will set.

Symptoms There may be no visible symptoms to the driver, other than the MIL (Check Engine / Service Engine Soon) illumination.

Causes
A code P0137 may mean that one or more of the following has happened:
  • Faulty O2 sensor Exhaust leak near the rear sensor
  • Plugged catalyst
  • Short to voltage on O2 signal circuit
  • High resistance or open on O2 signal circuit

  • Possible Solutions
  • Replace faulty sensor
  • Repair exhaust leak near the rear sensor
  • Check for restriction in catalyst and replace as necessary
  • Repair short, open, or high resistance on o2 signal circuit
The other code is your crankshaft position sensor. You need to replace both of the sensors and the check engine light will go off.

Car keeps shutting off


I can solve part of your problem. I would check the crakshaft position sensor. These are located behind the harmonic balancer. This will caues the engine to shut off when the engine is at opperating temperature. As for your fluctuating fuel needle, I have a question for you. Do you use Shell gas at all? If you do then their detergents in the gas has eaten away at your fuel sending unit and it needs to be replaced. Only use Esso, PetroCanada (if you are in Canada) or Chevron gas if at all possible. Shell has had dealer bulletins about GM and Dodge not using their gas. The check engine light is usually a faulty O2 sensor but replace the CP sensor first.

Please Help... p0404 and p0137 Error Codes (1999 Saturn SL1)


hey if you truely think it is your egr valve unhook it and if that is the problem then when it is unhooked it should run better and the codes should not come up. hey if you cahnged the 1 o2 sensor and not the other you probably made the code for the one u repalced come up again. i would recommened that you change both of the o2 sensors at the same time. try checking if your catalatic convert is plugged. how you do this is take a dollar bill and hold it at the end of your tail pipe while it is idleing and if the dollar bill stays still you have a plugged catalatic converter.
