What is the code for an O2 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.
What does a code p0134 on an oxygen sensor mean?
A code P0134 may mean that one or more of the following has happened: Bad O2 (oxygen) sensor. Bad heater circuit in the O2 sensor. Wiring or connector to the sensor frayed / broken.
What should I know about the p0404 code?
CAME UP EGR SYSTEM FAILED FAILED EGR POSITION SENSOR OPEN OR SHORT CIRCUIT CONDITION FAILED EGR VALVE FAILED EGR POSITION SENSOR APPLICABLE OK SO THIS IS WHAT CAME UP WHEN THEY READ THE CHECK ENGINE LIGHT SOOOO I HAVE CHANGED THE EGR VALVE AND STILL WONT GOT PASS 10MPH AND JUST STUMBLES ALL OVER ITS… Need more help with a p0404 code?
What causes a p0154 code on Bank 2?
Potential causes of a P0154 code include: Faulty bank 2,1 Oxygen sensor. Holes in exhaust near oxygen sensor. Short to voltage or ground on signal circuit. Open or high resistance in signal circuit. Wiring harness chafing/rubbing on exhaust components. Water/oil intrusion at O2 sensor connector.
Is the p0404 valve on my Malibu gone?
I have a 2002 Chevy Malibu LS with the 3.1L V6 engine. I had a p0404 code and when I did my tune-up recently, I went ahead and replaced the EGR valve. However, after two days of normal driving (approx. 70mi each day), the code has not gone away.
What does the OBD code p0404 mean?
What the P0404 code means. P0404 is an OBD-II generic code that the engine control module (ECM) detected the engine exhaust gas recirculation (EGR) valve or sensor is out of specification range or its performance has gone out of specification parameters.
What does the code p0134 on the ECM mean?
Code P0134 is triggered when your vehicle’s O2 sensor (bank 1, sensor 1) is malfunctioning. The Engine Control Module (ECM) detects that the Oxygen (O2) sensor is at a standstill and is not accurately reading the amount of oxygen in the exhaust.
What is the p0404 exhaust gas recirculation circuit range?
Hello, I have a 1998 Sonoma SLS 4.3 auto, 4×4 with 150,000kms, I have been recently been having issues with the truck surging, revving up & down slightly & is very sluggish. I put it on a 3130 scanner & the code that came up was P0404 Exhaust Gas Recirculation Control Circuit Range Per…

What does error code P0134 mean?
Code P0134 is triggered when your vehicle’s O2 sensor (bank 1, sensor 1) is malfunctioning. This error in the oxygen sensor causes the ECM to misread the amount of oxygen and fuel coming through the exhaust, which inhibits it from ensuring the optimal fuel ratio.
What causes a P0134 code?
What does code p0134 on an OBD mean?
Check engine light illumination Poorly running/engine missing A code P0134 may mean that one or more of the following has happened: Bad heater circuit in the O2 sensor Wiring or connector to the sensor frayed / broken Blown heater circuit fuse Holes in the exhaust system The most common fix is to replace the oxygen sensor.
What does it mean when trouble code p0138 is set?
When trouble code P0138 is set, this indicates that there is a high voltage (steadily above .9 volts) for more than 10 seconds indicating a lack of oxygen in the exhaust stream and an abundance of fuel at sensor 2 on the bank 1 of the engine.
How does the p0134 O2 O2 sensor work?
As the sensor warms up the resistance is lowered and it starts producing voltage based on the oxygen content in the exhaust.
What does p0138 mean in a catalytic converter?
O2 Sensor Circuit High Voltage (Bank 1, Sensor 2) What Does P0138 Mean? Oxygen sensor 2 is the downstream oxygen sensor in relationship to the catalytic converter. It measures the amount of air and fuel coming out of the catalytic converter to ensure the catalytic converter is functioning properly.
