Repair Urgency: Get this code fixed as soon as possible. Diagnosis: It is important to complete the entire diagnostic process when diagnosing the P0158 code. This DTC can be triggered by a faulty oxygen sensor, damaged wiring, faulty coolant temperature sensor, or high fuel pressure.
How do I fix error code P0158?
What repairs can fix the P0158 code?
- Replace the rear oxygen sensor.
- Repair any oxygen sensor wires that have shorted out, are broken or exposed.
- Make necessary repairs to remedy the excessive fuel pressure.
- Replace engine coolant temperature sensor if it is necessary.
Can I drive with a P0158 code?
It’s relatively safe to drive your vehicle for a short period of time if the P0158 code registers in your vehicle’s memory. However, if you continue to neglect this issue, your vehicle’s catalytic converter might get damaged. Once it does, you risk failing your emissions test.
How do you fix a high voltage O2 sensor?
Zitat von Youtube: Make sure the new injector has new seals. And never use the old seals. Over when you change the fuel injectors. Change them all as a set otherwise the engine will run unevenly.
What would cause a high voltage O2 sensor?
The high voltage condition from the O2 sensor is indicating a lack of oxygen in the exhaust or other related problems, such as a leaking fuel injector or a broken up catalyst inside.
What is Bank 2 oxygen sensor?
Bank Two is the passenger side. Sensor 1 on Corvettes is always the sensor that is closest to the exhaust port of the engine. Bank Two is post catalytic converter. Bank 1 Sensor 1 – Driver side before converter (front) Bank 1 Sensor 2 – Driver side after converter (rear)
Is bank 2 sensor 2 upstream or downstream?
Bank 2 Sensor 1 means Upstream Left/Front; Bank 1 Sensor 2 means Downstream Right/Rear; Bank 2 Sensor 2 means Downstream Left/Front.
Is Bank 1 sensor 1 Left or right?
Since Bank 1 is the rear one toward the firewall and has the sensors labeled RH it must be considered the right side of the engine. Conversely Bank 2 is toward the radiator, the front of the vehicle, and has the sensors labeled LH, that makes it the left side of the engine.
Which side is Bank 2 sensor1?
Bank 2 Sensor 1 (a.k.a. B2S1) is located on the side of the engine with cylinder 2 in the firing order and the O2 sensor situated in front of the catalytic converter. Depending on the car’s make and driver orientation, it could be found on either the driver or passenger side of a vehicle.
What does Post Catalyst fuel Trim system Too Lean Mean?
If you see this generic code, it’s likely a problem in the exhaust system. Your vehicle is getting too much air and not enough fuel, creating a lean condition that disrupts the fuel efficiency of your vehicle.
What does a high voltage code mean?
When trouble code P0138 is set, this indicates that there is a high voltage (steadily above . 9 volts) for more than 10 seconds indicating a lack of oxygen in the exhaust stream and an abundance of fuel at sensor 2 on the bank 1 of the engine.
What can cause a false O2 sensor code?
Bad Spark Plug, Wire, or Fuel Injector
Any of these can cause one or more cylinders to misfire. Because the oxygen in that cylinder isn’t burned up, the extra oxygen in that cylinder winds up passing over the O2 sensor.
