2002 Alero check Engine light Codes P0132, P0137

Old question that must have been resurrected by spam, but I fixed the dreadful written English tossed in some CAPS and a few SPACES! It looks pretty now.

All questions need full 'year make model', rather than 'year make, engine size'.

Anyway, there is this thing called Google. It knows everything. Here is your first code. Just copy and paste the others in and press enter.

What Does P0031 Mean?

The P0031 code is a result of the bank 1 HO2S1 (pre catalytic converter heated oxygen sensor) heating element having low voltage. Heated O2 sensors have a seperate heater inside the sensor to get them to operating temperature quickly.Oct 1, 2018

OBD2 Codes - P0031 - Meaning, Causes, Symptoms, & Fixes

..

P0137 is a bank 1 sensor 1 O2 sensor circuit low input . Low fuel pressure , water in fuel , too much ethanol in fuel , leaking intake gasket or vacuum lines can set this code and the others as well .

Hello Hazem Hammad,

Check out the exhaust system...

You might have a catalytic converter or muffler
blocking the OUT-FLOW.

Unless you are into DIRTY jobs... and LIQUID WRENCH...
Consider your local friendly muffler shop...

JUST MAKE SURE you know your
PRICES BEFORE going in...

A wee bit of dirt can save A BUNCH of money
(if you don't drop the car on yourself).

Choose wisely... be safe!!

1999 HONDA ODYSSEY 3 5L V6 Catalytic Converter RockAuto

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.

Replace the catalitic converter.

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.

No, no need to go the expense.

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.

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.

yes egr valve is a common thing on this saturn. very pricy and yes you need the rear o2 sensor good luck i have a used egr if interested off a sl2
