This will not affect the way the engine accelerates. The tips or ends usually plug up restricting fuel flow resulting in a lean condition. However, it will go away when the lean codes are repaired. Below is a list of the more common Toyota engines you will see. The first time I saw this car was from a referral by my local trans shop. The problem may be on a much smaller scale where the computer on the Toyota Corolla can compensate for the lean condition and the driver may never feel a hiccup while driving. P0158 Toyota Auto Trouble Code P0158 Toyota Auto Trouble Code on vehicles with electronically controlled automatic transmissions, the 3-4 shift solenoid is responsible for actuating the hydraulic circuits to activate clutches or bands that change gears inside the automatic transmission.
In addition the changes of the amount of air coming into the engine or driving conditions change very fast as the driver accelerates and lets off of the gas pedal so the response time must be quick , fast and accurate. I was told my catalytic converter is bad. Again, normal fuel trims are plus or minus 7%. P1310 Igniter Circuit — No. This vehicle also has a history is flagging P2195, P0138, P0031 along with the P0171 lean code. If not, go tho a dealer and tell them that you want Oxygen Senso Bank 2, Sensor 2, and have them tel you where it is. Also, you can watch the engine load under wide open throttle as it should go about 85 or 90%.
Normal numbers at idle and high positive numbers under a load indicate a faulty mass air flow sensor. P0505 Idle Speed Control System. So it is always a good idea to replace the air filter anytime the mass air flow sensor gets replaced. Posted on Feb 05, 2009 On this make the warning lights all come on together, the check engine light is the cause of all. Inspect for holes, wiring harness making contact with exhaust, etc. P0130 Heated Oxygen Sensor Circuit — Bank 1 Sensor 1.
After removing it, look toward the center of the newly exposed area and you will see 2 finger-like objects projecting out from the engine with wires coming out of each. There will be 10 bolts holding it on 10mm, I believe. The video above shows how to check and change blown fuses in the engine bay of your 2008 Toyota Highlander in addition to where the fuse box diagram is located. My guess would be the sensor has shorted out internally, or you have a wiring problem between the sensor and the engine computer. Specifically, it is as follows: Oxygen Sensor Circuit has High Voltage; Bank 2 Sensor 2. You can also watch the fuel trims under a load too.
I replaced it with a denso part. However, there three common causes for this lean condition and P0171 code and I will go over each of them in detail. If you have one injector that you suspect is bad or plugged up causing the engine to misfiring, you can swap that fuel injector with another fuel injector from a different cylinder to see if the misfire code or misfire condition moves along with the fuel injector. The one on the left passenger-side is bank 2, sensor 2. The calculated load reading should increase to 85% or higher on a wide open throttle acceleration. This problem should be addressed as soon as possible to avoid drivability issues. So it it has a vacuum leak, it will show up at idle or lower engine rpms and usually cause a surging or high idle condition if the vacuum leak is large enough.
Two wires are dedicated to the heating element and two wires are dedicated to the sensor. A discrepancy in voltage levels between the main cpu and the sub cpu. Note: This is the same 2. Specifically, it is as follows: Oxygen Sensor Circuit has High Voltage; Bank 2 Sensor 2. A P0158 Toyota definition:a fault at the post-cat o2 sensor on bank 2 second sensor back on bank 2 , indicating that the signal voltage is too high.
First is a brief overview of this code. I am done just throwing money at it here and there. P1200 Fuel Pump Relay Circuit. If so, it indicates that the trouble area has not been repaired correctly. Technical Tip: While watching the fuel trims on your scanner, engine fully warmed up, step on the brake pedal.
P0158 Toyota Master engine problem can be occur defective fan clutches are a common and often overlooked cause of engine overheating. P0156 Heated Oxygen Sensor Circuit — Bank 2 Sensor 2. With the car running I start wiggling and tugging on the sensor wires. Bank 2 is simply the other bank. The list of automotive Makes at the right edge of the screen. If it is a 4 cylinder engine, there is only one bank. Eventually slippage reaches the point where effective cooling is no longer possible and overheating results.
P0158 trouble code definition Oxygen Sensor Circuit High Voltage Bank 2 Sensor 2 What the P0158 code means The P0158 trouble code appears when the sensor has remained at a high voltage for too long. Sometimes you can clean the sensor element but most of the time replacement is necessary. When P0158 came on, I had another error code about small evap leak. P0306 Misfire Detected — Cyl. Good to know I am thinking I will just take it in and get a professional diagnose. I'm thinking maybe the cat is toast now since I have been driving it at a rich condition for a while now. P0304 Misfire Detected — Cyl.
The information contained on this site is presented for informational purposes only. P0135 Heated Oxygen Sensor Circuit — Bank 1 Sensor 1. I guess I can try that. P0420 Catalyst System Efficiency below Threshold. They should be able to figure out if the component needs to be replaced or if there is a short or some other problem with your Highlander.
