Installed new oxygen sensors but light is still on


You need to clear the check engine light with a scanner. If you clear it and light comes back on check for a new code number. If you bought your parts locally the parts store should scan/clear your codes for free.

Check Engine LIght on- Code PO1400


I could not find any code P01400 (normaly P codes are only 4 characters long)...

P0140 is Oxygen Sensor Circuit No Activity Detected Bank 1 Sensor 2 (most likely the sensor has gotten damp or bad gas and has corroded a bit, reset the sensor and run some gas additive through a full tank of gas. this should clear it up, but if it comes back, then the sensor might need to be replaced)

If the vehicle sat for a while and was not run, it is most likely this O2 sensor. You may also notice it running a little rougher, or going through more gas than normal.

The engine light and VSC light are on (Vehicle Singapore 2004 Lexus RX 300. Diagnostics report Error code P0037


your o2 sensor is bad. vsc will go on for any small DTC displayed on the MIL (cel)

P0037 LEXUS P0037 LEXUS - Oxygen Sensor Heater Control Circuit Low Bank 1 Sensor 2 Symptoms - Engine Light ON (or Service Engine Soon Warning Light)
Possible causes - Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit open shorted to ground
- Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit poor electrical connection
- Faulty Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit
- Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit fuse
- Faulty Engine Control Module (ECM) When is the code detected? The P0037 is set when the ECM detects an excessively low voltage through the heated oxygen sensor heater circuit P0037 LEXUS Description Oxygen Sensors (O2S) or Heated Oxygen Sensors (HO2S) need to reach a minimum operating temperature of 750 degrees F to produce an accurate voltage signal. The faster the heated oxygen sensor reaches that temperature the faster the sensor will start sending an accurate signal to the Engine Control Module (ECM).

In order to achieve the require temperature, a heater element is included inside the heated oxygen sensor. The ECM controls the heated oxygen sensor heater element based on signals from the engine coolant temperature and engine load. The ECMcontrols the heater element circuit by allowing current flow to ground.

The ECM monitors the voltage signal received through the heater element circuit and determines the state of the circuit by comparing the voltage detected with the factory specifications.

Check engine light on- auto zone scanner shows error code p0053 probable cause: 1.-check circuit fuse 2.-relay defective 3.-check circuit wiring Where are fuse and relay located?


The code P0053 is for your Bank 1 Oxygen Sensor, the closest Oxygen Sensor to the engine, connected to the Exhaust. Replace your Oxygen Sensor, clear the code, and see if it comes back.

Check engine light is on and it reads Misfire on #2 cylinder. Also oxygen sensor bank2 sensor 1 and Bank 1 sensor 3 behind the converter. Engine running rough.


the engine miss fire can cause the other codes to set. you need to repair the miss fire and clear all codes after the miss is repaired then see if the 02 sensor codes return. the miss fire is probably a bad spark plug wire a good tune-up should take care of it ........HAVE A GREAT DAY

Code po157 what does it mean and how do i fix it?


P0157 Oxygen Sensor Circuit Low Voltage (Bank 2 Sensor 2)

I would try replacing the Oxygen sensor, then clear the code.

The O2 sensor would be the after the catalytic converter ( sensor 2) on the exhaust pipe of the number 2 cylinder uses ( bank 2).

My engine light stay on and there are four codes. I changed the bank 1 sensor 2 and a new gas cap and also theegr oxygen sensor but the engine light is still on. any suggestion?


did you clear the light? if so what are the codes? codes don't mean a certain sensor is bad, only that there is a problem in that sensors circuit, it can be the sensor or the wiring or a mechanical fault in the engine or the computer, which is rare.

I am having trouble with my speedometer not working occasionally and now my seat belt light is coming on sometimes too. Is this the instrument panel cluster? Or something else? 1998 Dodge Neon. Backstory is as follows: -We take very good care of it and have one dedicated mechanic. -It has only had two owners; my parents and I. -We replaced the battery 2 months ago. -Mechanic checked to make sure the speedometer sensor was working. -We have had issues with the radio for years where it will randomly turn on and off, typically brought on by a stuffed trunk OR wet weather. -The speedometer works until we hit a bump and then the needle flies up and down or sometimes just stops working all together. -Mechanic has made mention of there being some Chrysler specific battery cable that is a smaller side cable and it is not in good condition. -Currently, my problem is that I can't find an old 1998 Dodge Neon in the salvage yard because yards are doing a lot of 2002 and newer vehicles and automatically crushing the others. The meat and potatoes of my question is what direction do I go in? And what of these symptoms ties to each other? And will adding new solder to the points on the panel fix it or is it something else? I'm trying to find least expensive to most expensive options and I'm rather handy but can't drop an engine or transmission or anything so keep this in mind. My handiness ends at resoldering the pins BUT I do have a mechanic I trust, but I fear that maybe I'm not combining symptoms properly. I have the money to repair an item I KNOW is wrong but not to chicken hunt around for problems.
