OBD2 CODES P0131, P0137, P0151

RUNS PERFECT, AFTER 4 MILES DRIVEN ENGINE LOCK OF POWER SURGE. AS SOON THROTTLE PEDAL IS RELEASED TO 1/3 (30 MPH)IT RUNS PERFECT AGAIN. SOUNDS LIKE A BAD CATALYTIC BUT IS NOT. WHILE DRIVING IT I TURN IGNITION OFF AND ON AND FIX THE PROBLEM BY ITSELF FOR A MINUTE OR TWO AND AGAIN THE SAME OLD PROBLEM. AFTER 8 WEEKS SEARCHING SWAPPING AND INSTALLING NEW COMPONENTS I WENT TO CHEVROLET DEALER THEY INSTALL A REMAN. ECM. SAME ****. I TOOK THE ECM AND GET IT INSTALLED ONTO ANOTHER 97 ASTRO THAT IS WAS RUNNING RIGHT. GUESS WHAT?, THAT OTHER VAN RUNS PERFECT.
SWAPPED THE ECM BACK TO THE ORIGINAL VAN AND IS RUNNIG BAD. ENGINE WIRING HARNESS FAILURE SOMEWHERE?. THANKS.

On my 1998 Infinity QX4 I was getting randomly both of P0131 & P0151
This was caused by bad grounding between the intake manifold & the main ground cable.
Installing a thick jumper wire (#10 0r #8) between the intake manifold & the Cylinder head or Main Battery ground cable fixed the problem

Check for every posible loose ground arrownd the engine block
i had foud that many times and technicians have very hard time to find it if you see some thing wires atached to the engine block pull gently on it to see if they are open internally
and check also for clean and tie circuits at batterie and starter

Why does po131 keep returning after i replaced bank 1 02 sensor ? i clear codes and en about a week code returns data looks good


See causes
P0131 OBD-II Trouble Code Technical Description

Oxygen O2 Sensor Circuit Low Voltage (Bank 1, Sensor 1)
What does that mean? Essentially the same as P0136 and P0137, a P0131 code refers to the first oxygen sensor on Bank 1.
P0131 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 1 is located in front of the catalytic converter.
Symptoms There may be no visible symptoms to the driver, other than the MIL (Check Engine / Service Engine Soon) illumination.
Causes A code P0131 may mean that one or more of the following has happened:

  • Faulty o2 oxygen sensor
  • Short to voltage on O2 signal circuit
  • High resistance or open on O2 signal circuit
Possible Solutions
  • Replace faulty sensor
  • Repair short, open, or high resistance on o2 signal circuit

Fault code 151


We guess DTC P0151... essentially the same as P0136 and P0137 and P0131, a P0151 code refers to the first oxygen sensor on Bank 2 . P0151 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 2 Sensor 1 is located in front of the catalytic converter.

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

A code P0151 may mean that one or more of the following has happened:
Faulty o2 oxygen sensor
Short to voltage on O2 signal circuit
High resistance or open on O2 signal circuit

Possible Solutions:
Replace faulty sensor
Repair short, open, or high resistance on o2 signal circuit

HI ghosthunter6 codes P0131&P0137&P0341 indicative of having electrical short .
P0131 Front Heated Oxygen Sensor Bank 1 harness is open or shorted .
P0137 Rear Heated Oxygen Sensor Bank 1 harness is open or shorted .
P0341 Camshaft position sensor harness or connectors (The sensor circuit is open or shorted) .
code B1218 horn relay coil circuit short to voltage battery .
IT could be cousin problem with other sensors .
First replace horn relay and clear E C M codes
IF problem and codes P0131&P0137 come back you need o2 sensors .put I don't thank so.
YOU MUST REPLACE HORN RELAY .OK

good luck

Not Ready for Smog test


it is not how many miles but the type of driving.

here is a OBD2 drive cycle test.

Generic OBD II "Drive Cycle" Most OBD II ("On-Board Diagnostics II") diagnostic monitors will run at some time during normal operation of the vehicle.
However, to satisy all of the different Trip enable criteria and run all of the OBD II diagnostic monitors, the vehicle must be driven under a variety of conditions. The following drive cycle will (theoretically) allow all monitors to run on (??) vehicle. (Note: Drive cycle specifics vary by vehicle!)
  1. Ensure that the fuel tank is between 1/4 and 3/4 full.
  2. Start cold (below 86°F /30°C) and warm up until engine coolant temperature is at least 160° F (typically requires at least one minute; up to 3 minutes).
  3. Accelerate to 40-55 MPH at 25% throttle and maintain speed for five minutes.
  4. Decelerate without using the brake (coast down) to 20 MPH or less, then stop the vehicle. Allow the engine to idle for 10 seconds, turn the key off, and wait one minute.
  5. Restart and accelerate to 40-55 MPH at 25% throttle and maintain speed for two minutes.
  6. Decelerate with using the brake [or the clutch!] by coasting down to 20 MPH or less, then stop the vehicle. Allow the engine to idle for 10 seconds, turn the key off, and wait one minute.

Engine surge at 45-55 mph on 2002 Silverado 5.3l engine


I would start looking for a vacuum leak. Check all the vacuum lines for cracks or breakage. Spray penetrating fluid on them until you hear the engine start to stumble then focus the spray on that area until you are able to pinpoint the location of the leak. Best of luck,my friend, Dana
