Gm trouble code list


P0140 - 02 Sensor Circuit No Activity Detected (Bank 1 Sensor 2)
The causes for a P0140 code are few and unless the wire/s has been damaged, replacing the sensor is usually the smartest thing to do.

I replaced both 02 sensors and still keep get a service engine soon light, with a code p0140 why?


The code is indicating that the reading the computer is picking from the rear O2 sensor is off. This can be caused by many things in the engine, rich fuel mixture, lean fuel mixture. A high-end scan tool needs to be hooked up and a diagnosis done.

P0146 pd means pending code
Pending codes and DTCs? Posted on November 12, 2010 by fcrmaster
When reading codes from your vehicle the fault code reader may show them as pending codes or normal Diagnostic Trouble Codes (DTC).
Pending codes (also known as continuous monitor codes) will be registered when an intermittent fault occurs. If that fault does not happen again after x number of start/stop cycles, the ECU will erase the code from memory. If the fault is persistent it becomes a DTC.
If you have read pending codes it is advisable to check the codes again after a week or so. If there is no apparent problem with the vehicle it is safe to erase the codes too and check back. But always make a note of any fault codes with the date and mileage of a vehicle.
If the codes read include a DTC then you need to investigate further. This you can either do yourself or advise your garage. If, again, you don't see an apparent problem (depending n the severity of the code) with the vehicle you can note the codes down and erase them. Then check again after a week or a few days depending on how often the vehicle gets used. If a repair has been made (previous owner) the DTC may just not have been reset after the repair.
The other numbers behind the code 01/06 , 02/06, 03/06 , 05/06 ,04/06 These don't mean anything . cheap code reader .
DTC P0140 HO2S Circuit Insufficient Activity Sensor 2
DTC P0146 HO2S Circuit Insufficient Activity Bank 1 Sensor 3
DTC P0171 Fuel Trim System Lean Bank 1
DTC P0174 Fuel Trim System Lean Bank 2
Sorry but this is something you should take to a qualified repair shop that has a diagnostic tool that can view sensor scan data.

Check engine light is on, diagnostic code p0140 keeps comming up.


I had this problem with my 05 Trailblazer and it happened around 50k miles. The oxygen sensor needs to be replaced and the part costs about 90 bucks but atleast you will have you're check engine light off.

Chevy wont start


sounds like seprate issues check for fuel pressure, and spark. the code refers to a poss bad o2 sensor wich would be a seprate issue since o2sensors typically wont keep it from starting, just use alot of gas. good luck
