Your car has oxygen (O2) sensors that measure the amount of oxygen present in your exhaust. Based on the measurements these sensors take, the O2 sensor will fluctuate between a high (rich) and low (lean) voltage reading. Your Engine Control Module (ECM) uses the voltage levels provided by your O2 sensors to regulate your engine’s air/fuel mixture. If you are seeing code P0130, it means that the O2 sensor before your catalytic converter on bank 1 is malfunctioning.

P0130 Causes

  • Faulty Bank 1 O2 sensor 1
  • Exhaust leak in front of sensor 1
  • Intake leak
  • Corrosion in connecter
  • Frayed or broken wiring

P0130 Symptoms

  • Check Engine Light
  • Decrease in MPG
  • Increased tailpipe emissions
  • No noticeable adverse conditions in some cases

How Do I Fix Code P0130?

With a P0130 code, the first step is to get it properly diagnosed to figure out what is causing the malfunction in the oxygen sensor system. Using the live data function of the FIXD sensor and app allows you to read and analyze engine data to properly diagnose a P0130 code.

If the sensors are all reading correctly, check for an exhaust leak. If any of these conditions exist and you’re not comfortable further diagnosing this issue at home, we recommend finding a RepairPal-certified shop to pinpoint the problem and give an accurate estimate for repairs. 

These shops can not only help you figure out what’s going wrong before you waste time and money on the wrong parts, but they also offer a minimum 12-month, 12,000-mile warranty and stand behind all their estimates with guaranteed fair pricing.

How Much Does It Cost to Fix Code P0130?

If you take your car to a shop for diagnosis, most shops will start with an hour of “diag time” (the time spent in labor diagnosing your specific issue). Depending on the shop’s labor rate, this typically costs somewhere between $75-$150. Many, if not most, shops will apply this diagnosis fee to any required repairs if you have them perform the repairs for you. From there, a shop will be able to give you an accurate estimate for repairs to fix your P0130 code.

DIY Steps to Diagnose Code P0130

If you’d like to try to fix code P0130 at home without throwing money at parts, you’ll want to follow the steps below for proper diagnosis. Complete diagnosis may require some specialized equipment beyond what the FIXD Sensor can provide, but the biggest challenge for this repair is that internal engine issues could be the root cause of this code. As such, this diagnosis and repair should not be attempted by beginner DIYers. 

DIY difficulty level: Intermediate

This repair requires mechanical knowledge and is not recommended for beginners.

Tools/parts needed (our top picks from Amazon):

STEP 1: USE FIXD TO ENSURE NO OTHER ENGINE CODES ARE PRESENT.

Scan your vehicle to verify P0130 is the only code present. If other codes are present, they must be addressed first.

STEP 2: INSPECT O2 SENSORS AND WIRING. 

Visually check the electrical connections, wire harness, and metal tabs in terminals for any damages. If any damage is found, replace the oxygen sensor.

STEP 3: CHECK OXYGEN SENSOR(S) LIVE DATA WITH FIXD.

Warm up your engine. Using FIXD Live Data, look at your O2 sensor (bank 1, sensor 1) voltage. Note if the O2 sensor is rapidly or slowly switching from low to high voltage. This could indicate a faulty O2 sensor.

STEP 4: INSPECT VACUUM LINES.

Check for any vacuum leaks in the engine or any holes in the exhaust that could lead to air escaping from the engine. Repair any leaks or holes you find.

STEP 5: CONSULT A PROFESSIONAL.

If at this point the vehicle is still setting the same code, you may have a more serious problem with your car’s oxygen sensor system, and you should bring the vehicle to a certified shop to have further diagnostic work performed.  

Common P0130 diagnosis mistakes

Replacing the O2 sensor without checking for any intake or exhaust leaks or loose connections.

    1. Was fixed on september 26, 2018 at Blackstone auto repair on Haines road in Levittown.

      1. Thanks for the information. I think that I’ll have to replace the O2 sensor. In fact, I’m going to replace all 4 02 sensor’s. I’m having problem’s with coolant temperature sensor. It’s hard to locate on my Audi A4, 2004, 3.0 engine. Are the electrical clips color coded. U know like is some of the sensor’s are green, and others are tan or black. Is there a reason why there’s a difference in those colored sensor’s ?

        1. Of you have problem on cts sensor you’ll not authorities to cold start as well as other times the o2 sensor has not any relation with cts

        2. The only known issue im having is my blower motor not wanting to work unless theres pressure on the wiring connecting it to my dash. Im not too car savvy so i have no clue what its called. Its not the plug physically connected to the motor. – ford fusion 2011 hybrid

    2. Have replaced O2 sensor and check engine light came on after only128 miles.

    3. Where is P0130 sensor located?

      1. code p0130 is the 02 sensor bank one sensor one located on the passenger side the one on the top there’s 2 of them on each side the p0130 is the top one on the passenger side

        1. Dean,

          How do you determine which one of the 2 O2 sensors are faulty if I only get a P0130 engine code? I would assume one is the upstream and one is the downstream but which one gives the P130 engine code?
