P1134 Possible Causes

• Faulty Heated Oxygen Sensor (HO2S), Bank 1 Sensor 1
• Open or short circuit in Bank 1 Sensor 1 HO2S wiring harness
• Poor electrical connection in Bank 1 Sensor 1 HO2S circuit

How to Fix Code P1134?

Start by checking the “possible causes” listed above. Visually inspect the corresponding wiring harness and connectors. Look for damaged components and check for broken, bent, pushed out, or corroded connector pins.

Possible Symptoms

• Check Engine Light on (or Service Engine Soon warning light)

P1134 Meaning

The Powertrain Control Module (PCM) monitors the activity of the Heated Oxygen Sensor (HO2S). During the monitoring period, the PCM counts the number of times the HO2S switches from rich to lean and from lean to rich, and adds up the time it took to complete all transitions. With this information, an average time for all transitions can be determined. The PCM then divides the rich-to-lean average by the lean-to-rich average to obtain a ratio.

P1134 ACURA Possible Causes

P1134 BUICK Meaning

The Powertrain Control Module (PCM) monitors the activity of the Heated Oxygen Sensor (HO2S). During the monitoring period, the PCM counts the number of times the HO2S responds from rich to lean and from lean to rich and adds the time it took to complete all transitions. With this information, an average time for all transitions can be determined. The PCM then divides the rich to lean average by the lean to rich average to obtain a ratio.
