The automobile fault code P1134 can be diagnosed and fixed within an estimated repair time of 1.0 hour. The cost of the repair will depend on the hourly rate charged by the auto repair shop, which typically ranges between $75 and $150 per hour.

The P1134 fault code refers to the Heated Oxygen Sensor (HO2S) Transition Time Ratio on Bank 1. The Powertrain Control Module (PCM) monitors the activity of the HO2S during a specific period.

It counts the number of times the sensor switches from a rich to lean mixture and vice versa, while also measuring the time it takes for these transitions to occur. By calculating the average time for all transitions, the PCM can determine a ratio by dividing the rich-to-lean average by the lean-to-rich average. This ratio helps the PCM assess the performance of the HO2S on Bank 1.

What are the possible causes of fault code P1134 and how can I visually inspect them?

If you’re experiencing the dreaded Engine Light ON or Service Engine Soon Warning Light, fault code P1134 might be the culprit. This code is often caused by a faulty HO2S Bank 1 Sensor 1, an open or shorted HO2S Bank 1 Sensor 1 harness, or a poor electrical connection in the HO2S Bank 1 Sensor 1 circuit. To visually inspect these potential causes, check the wiring harness and connectors for any damage. Look out for broken, bent, pushed out, or corroded pins on the connectors. Don’t forget to examine the components for any signs of wear and tear.

How can I determine if the HO2S Bank 1 Sensor 1 harness is open or shorted?

If your engine light is on and you suspect a problem with the HO2S Bank 1 Sensor 1, there are a few steps you can take to determine if the harness is open or shorted. First, visually inspect the wiring harness and connectors for any damage. Look for broken, bent, pushed out, or corroded pins on the connectors. These could be signs of an open or shorted circuit. If you find any issues, it’s important to fix them to ensure proper functioning of the sensor.

What steps should I take to check for damaged components and inspect the wiring harness and connectors for fault code P1134?
