P0134 Acura Code - Air/Fuel Ratio Sensor 1 Heater System Malfunction
Quick Answer
The Air/Fuel Ratio (A/F) Sensor (Sensor 1) is activated by warming the element with a heater and by maintaining a steady high temperature to accurately calculate the air/fuel ratio. Common causes include Faulty Air/Fuel Ratio (A/F) Sensor (Sensor 1), A/F Sensor (Sensor 1) harness is open or shorted, A/F Sensor (Sensor 1) circuit poor electrical connection. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

2006 Acura TL (3.2); Automatic; No Sports Package
I had some car trouble, when I pressed the gas, my car would
barely move. I took it to Auto Zone, here are the codes that showed up:P0134 – HO2S (B1) S1 Heather System Malfunction (No
Activity)P2251 A/F Sensor S1 V?r Circuit High Voltage
P2138 APP Sensor A/B (TP Sensor D/E) Incorrect Voltage
CorrelationP0134 HO2S (B1) S1 Heater System Malfunction (No
Activity)Code P0134 indicates that the Bank 1, Sensor 1 O2 electrical
circuit had no activity for a predetermined period of time.Auto Zone advised the part replacement is their Part # 13965
– Bosch. This is a front, upstream sensor (located before catalytic converter).I called my local Acura dealership to see what the price
difference is – if it’s minimal difference, I’ll usually pay for the dealership
part. I am a woman, maybe that’s silly! I know nothing about my cars and my dad
does any minor work to my car.The Acura Service Department said that they would need to
complete their own diagnostics test, while the car is running. They asked if
Auto Zone did the diagnostics test while the car is running – no they did not?
It was parked. They can’t get me in until Monday/Tuesday but my dad thinks he
can replace the part – thank you online forums! Every time I go to the
dealership, there’s always surprise parts I need so I feel like that’s why the
service department wants to complete their own diagnostics test… However…I then spoke to the Acura Parts Department and told them
exactly the information from the Auto Zone print out – gave the P0134 code; the
man seemed unsure. I told her it says Bank 1, Sensor 1. He quoted me a
different part. The Parts representative confirmed with the Service
representative for Bank 1, Sensor 1, that is the part however it’s a rear part.
Auto Zone says this is a front part. It’s a $200 part for the front and $130
for the rear. My dad says since it’s electrical, you cannot return it so I want
to make sure I get the correct part.Does anyone have any input?
1.
If a P0134 code reads for Auto Zone, shouldn’t
the Acura dealership come up with the same code? The codes are uniform to the
vehicle, correct?2.
Does anyone know if this is a front or a rear
part?
