Question about 1998 Volvo S70

1 Answer

P0136 hey - if I replace O2 sensor, and everything else would be ok with the entire system - the check engine light will go away by itself, or I need to reset it with some device?

    cool - thanks- is there a difference between front and rear o2 sensor, or it;s just universal fit?

    I did pull fuse - did the job - then I found out that driving cycles never reset on that car - I passed emission no problem - car is exept in GA

If you replace the o2 sensor and that is the problem of why the check engine light is on then yes it will reset on its own. this will take a few days of driving due to the computer running all its tests and all passing then light will shut off.
the code you have is for a bad o2 sensor or wiring to it, there are a couple of o2 sensors, this code is for the rear o2 sensor.

SOURCE: 2004 volvo s 60 check engine light on

I would replace the bad 02 sensor and also have the engine checked for a tune up and fuel injection purge. Make sure whoever does the repairs clears the ECM memory so the light will go out. Bad spark plugs and dirty fuel injectors can cause a rich condition that a weak 02 sensor can't keep up with.

Either get a OBD2 electronic reader and clear codes or try disconnecting battery for five minutes to reset. Good luck.

SOURCE: This thing has been a lemon. It is not passing

air filter,, mass air flow meeter,, put injector cleaner in tank a week before its next test, but fill filter with it first,,, have the car CPU sorted out,(very pricy) change the "cat" its likley to be a duff one by now,
if all fails,,, brop mechanic a good drink to look other way when hes testing the co level???
if the engine is worn out you will never get the co level low

P0136


Code 136 is for a problem with the O2 sensor mounted in the exhaust pipe after the catalytic converter.
The sensor would need to be checked with a scanner.

What does the codes p0442,p0136 &p0141 mean on my 2001 ford taurus it failed inspection for these codes


P0442 FORD - Evaporative Emission System Leak Detected Small Leak

Possible causes- Missing or loose fuel cap
- Incorrect fuel filler cap used
- Fuel filler cap remains open or fails to close
- Foreign matter caught in fuel filler cap
- EVAP canister or fuel tank leaks
- EVAP system hose leaking
- Fuel tank leaking
P0136 - O2 Sensor Circuit Malfunction Bank 1 Sensor 2
Possible causes- Rear Heated Oxygen Sensor Bank 1 harness is open or shorted
- Rear Heated Oxygen Sensor Bank 1 circuit poor electrical connection
- Faulty Rear Heated Oxygen Sensor Bank 1
- Inappropriate fuel pressure
- Faulty fuel injectors
- Intake air leaks may be faulty
- Exhaust gas leaks

P0141 FORD - O2 Heater Circuit Bank 1 Sensor 2

Possible causes- Faulty Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2
- Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit fuse

Bad o2 sensor code p0136


A code P0136 may mean that one or more of the following has happened:
  • Faulty O2 sensor or a leak in the exhaust close to O2 sensor
  • Short to voltage on O2 signal circuit
  • Open in circuit or high resistance caused by corrosion in the connector or other wiring to the O2 sensor.
The exhaust system should be inspected and the circuits to the sensor should be tested before spending any money on an O2 sensor. This COULD be caused by the sensor itself, but then again, maybe not.

Hello I hope you can help. My "service engine soon" light came on.I had trouble codes p0136 and p0304. We cleared the codes and the light has remained off, but the vehicle still runs poorly.My...


What does that mean? Essentially the same as P0137, a P0136 code refers to the second oxygen sensor on Bank 1. The O2 oxygen sensor produces a voltage between .1 mV and .9 mV. The ECM monitors O2 sensor voltage and determines if exhaust is lean or rich. O2 sensor voltage is high when exhaust is rich and low when exhaust is lean. The ECM monitors this voltage and increases or decreases fuel injector pulsewidth according to engine fuel/air ratio. If the ECM detects low HO2Sensor voltage for an extended period, it will set P0136 Conditions required to set: HO2 sensor voltage is low for longer than 2 minutes (minutes depend on model of vehicle. Could be up to 4 minutes)
Symptoms There may be no visible symptoms to the driver. Poor fuel mileage, possible misfire, depending on O2 sensor position when sticking.
Causes A code P0136 may mean that one or more of the following has happened:
  • Faulty O2 sensor leak in exhaust close to O2 sensor
  • Short to voltage on O2 signal circuit
  • Open in circuit resistance caused by corrosion in connector
Possible Solutions
  • Replace the second oxygen sensor on bank 1
  • Repair open or short in signal circuit
  • Clean corrosion from connector

A P0304 code means that the the car's computer has detected that one of the engine's cylinders is not firing properly. In this case it's cylinder #4.
Symptoms Symptoms may include:
  • the engine may be harder to start
  • the engine may stumble / stumble, and/or hesitate
  • other symptoms may also be present
Causes A code P0304 may mean that one or more of the following has happened:
  • Faulty spark plug or wire
  • Faulty coil (pack)
  • Faulty oxygen sensor(s)
  • Faulty fuel injector
  • Burned exhaust valve
  • Faulty catalytic converter(s)
  • Running out of fuel
  • Poor compression
  • Defective computer
Possible Solutions If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back.
If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.

Replace the O2 sensor first and see if that helps clear the vehicle up some. Some times these codes will trigger other codes and these are the issues that you will get.

I have a problem with check engine, in the scanner is appear the code P0136 O2 1/2 and I do not know which sensor is this, my car is a Mitsubishi Galant 1998 the engine es 4G64 2.4cc


p0136 02 sensor malfunction is (bank 1 sensor 2)-- replace 2nd 02 sensor thats in exhaust system. If it is a four cyclinder, then there is only one bank. if its a six then bank 1 is on the side of # 1 cylinder. bank 1 sensor 2 is after convertor. have a good day !

P0136, P1131, and P1151 codes on Ford Expedition 2000 4.6L


Your auto has four O2 sensors. Two upstream and two downstream; With two banks. Bank 1, sensor 1...and bank 2, sensor 1 are the two upstream (exhaust manifold before the catalytic). Bank 1, sensor 2 and bank 2, sensor 2 (other side of catalytic)

Code 1131= upstream; bank 1..sensor 1
Code 1151= upstream; bank 2..sensor 1
Code P0136 (generic code) bank 1..sensor 2 (questionable)

I wouldn't spend the money to purchase 3 sensors. Highly unlikely all three are bad; Cost is about $40/ ea.
Since there isn't a code for the cat's themselves, I would suspect the O2 circuit is malfunctioning. The rough idle is another clue.


Take an ohmmeter set it on X10 scale and measure the resistance from engine to body and body to negative post on battery terminal. You should read zero ohms (full needle deflection). If you do go buy two upstream O2 sensors. If you read
open or a high resistance run two straps from eng. to body...and body to neg.batt. post.

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.

Check engine light is on


P0136 = O2 Sensor Circuit Malfunction (Bank 1, Sensor 2)

Which would be the oxygen sensor after the converter.
