How do I fix code P0130?
What repairs can fix the P0130 code?
- Connect a professional scan tool.
- Check for any other faults.
- Analyze data from the ECM.
- Road test the vehicle.
- Check to see if the P0130 returns.
- Inspect all of the items listed above.
- Further diagnose the problem with the equipment listed above (scan tool, voltage meter).
What causes code P0130?
The P0130 code is triggered when the Engine Control Module (ECM) fails to properly detect activity from the O2 sensor. The O2 sensor transmits a voltage in relation to the amount of oxygen in the exhaust. 9 means the engine is “running rich” and has too much fuel and not enough air causing it to run hotter than usual.
What is the code for oxygen sensor?
P0138
Once the oxygen sensor stops performing as intended, the vehicle computer detects that and turns on the Check Engine light. This will usually have a diagnostic trouble code (DTC) of P0138. Typically, you’d take the vehicle into the shop, where they’d diagnose the issue and replace the oxygen sensor for you.
When does trouble code p0135 : heated oxygen sensor circuit?
When trouble code P0135: Heated Oxygen Sensor Circuit (Sensor #1) sets, it usually signals a problem with the internal heater of the upstream oxygen sensor. Thankfully, you can easily diagnose this trouble code without any expensive diagnostic test equipment, all you need is a multimeter.
Where are the oxygen sensors on a Toyota Corolla?
As you’re already aware, your 1.8L Toyota Corolla uses 2 oxygen sensors. One is located located before the catalytic converter and the second one is located after it. Both sensor’s are equipped with an internal heater and thus have 4 wires sticking out of them.
Where is the Black Wire on the O2 sensor?
The black ( BLK) wire, of the O2 sensor engine wiring harness connector, is the one that feeds power to the front O2 sensor’s heater element. CAUTION: Perform all of the oxygen sensor tests with a completely cold engine.
When to re-test front oxygen sensor heater test?
Re-check that you’re testing the correct wire and that the Key is in the RUN position (but don’t crank or start the engine) and re-test. If your multimeter still does not register 10 to 12 Volts DC, then you can conclude that HO2S 11 itself IS NOT bad since without power, the heater element won’t work.
