You have a burned Oxygen sencer, and the transmission pressure sencer is bad also. Your heater has a bad switchover circuit. Hope this helps.

How do i fix a code p0134 for my 1999 infintiy i30


code p 0134 refers to heated oxygen sensor(HO2S) 1 bank 1--no activity detected ===causes wiring open circuit ---heating inoperative ---HO2S Sensor
also refers to oxygen sensor (O2S) --no activity detected ===causes --- wiring---O2S
the HO2S is in the exhaust manifold before the cat converter
the O2S is after the cat converter
check the wires and connections , then replace either or both sensors

P1884 code 2005suzuki forenza P0420 P0134 P0138


code p 420 refers to cat converter system , bank 1--efficiency below threshold ===causes ---cat converter faulty---wiring --heated oxygen sensor (HO2S), 2 faulty
code p 0134 refers to HO2S 1 bank 1-no activity detected ===causes --wiring open circuit -- heating inoperative --- HO2S
also refers to oxygen sensor ( O2S) 1 bank 1--no activity detected == causes wiring ---O2S
code p 0138 refers to HO2S 2 bank 1--high voltage === causes ---wiring short to positive ---HO2S--- ECM
also refers to O2S 2 bank 1 high voltage === wiring short to positive O2S -- ECM
I do not have a listing for code p 1338 but I suspect that it will refer to the other codes in some way
first fix is to check the cat converter is operational ( not cracked and blocking the exhaust system)
next replace the HO2S sensor ( one before the cat converter ) and then the O2 sensor (the one after the cat converter)
all the codes will relate to problems in that area

Code p0156,p1131,p115,p0156 on my 2000 Ford taurus


P0156 - Problem with 0/2 circuit for downstream sensor of the front bank.
P1131 - Low activity of the upstream sensor for bank one. (rear)
P0115 - Problem with circuit for coolant temp sensor.

Just because you have codes for these sensors doesn't mean the sensor is the reason. The code merely tells you there is an issue in the circuit that needs to be troubleshooted accurately.

Code PO134


Trouble Code: P0134

HO2S-11 (Bank 1 Sensor 1) Insufficient Activity

Possible Causes:


HO2S heater is damaged or has failedHO2S signal or ground circuit has a high resistance conditionHO2S signal circuit is open or shorted to system power (B+)HO2S has failed (i.e., it is silicon, water or fuel contaminated)PCM has failed.Sounds like you need a new oxygen sensor,Bank 1 Sensor 1 is located on the exhaust manifold, closest to the front.Here's a link to the firing order,bank one is cylinder one side.Here's the part you need,here's how to replace.

Po134 trouble code


Hi:
This code refers to the front oxygen sensor on Bank 1. Basically the oxygen sensor is inactive. Here's why:
The powertrain control module (PCM) provides a baseline voltage of about 450 mV on the oxygen sensor signal circuit. When cold, the PCM detects the the internal resistance of the sensor is high. As the sensor warms up the resistance is lowered and it starts producing voltage based on the oxygen content in the exhaust. When the PCM determines that the time it took for the sensor to warm up is greater than one minute or that the voltage is inactive (not reading outside 391-491 mV it views the sensor as inactive or open and sets the P0134 code.Potential Symptoms
One or more of the following may occur:
  • Check engine light illumination
  • Poorly running/engine missing
  • Blowing black smoke
  • Poor fuel economy
  • Dying, stuttering
Causes 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
  • Blown heater circuit fuse
  • Holes in the exhaust system
  • PCM failure
Possible Solutions The most common fix is to replace the oxygen sensor. But that doesn't rule out the possibility of:
  • Rusted exhaust pipe
  • Inspect wiring & connector(s) for problems
  • Excessive amperage blowing heater fuse (still requires replacement of sensor but also replacement of blown fuse)
  • Replace PCM (only as last resort after all other possibilities are covered.
