Lexus is300 wont revv past 3000rpms has code p0103

P0103 OBD-II - Mass Air Flow (MAF) Circuit High Input
This DTC means that there is a problem with the Mass Air Flow High (MAF) sensor or circuit. A more technical description would be that the MAF circuit had higher than expected voltage (air flow). Other MAF sensor circuit DTC trouble codes are P0100, P0101, P0102, and P0104.

A code P0103 may mean that one or more of the following has happened:
- The MAF may be disconnected, or a wiring connection may be bad
- The MAF sensor may be damaged
- The vehicle computer may be faulty (very rare)

Feel free to contact us in this DTC P0103 code link, if you need additional details.

Hope this helps; also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using Fixya, and have a nice day.

How do u fix the P0141 ERROR CODE ON 2001 IS300? (Bank 1 Sensor 2)?

o2 sensor codes dont nessesarily mean the sensor is bad. other things can set this code, like a vacuum leak, an exhaust leak by that sensor, or a bit of water in the gas. I clear the code and wait to see if it comes back up. if it does then check for leaks. if there are no leaks it can be check with a scanner that will read datastreams from hte car computer. or manually check it with an ohm meter

How do i get my lexus is300 cds out?

the only way to get them out is to remove the unit from the car and disassemble it. if you replace the unit it will go to an exchange company and if you request it they will send your cd's back.

fuel is up. fuel pressure solenoid valve. It is located on the passenger side firewall. Has a couple of vacuum lines and a couple of wires. You will need a hand vacuum pump and a jumpers to test. I have never tested one, but read a couple of threads on the code. Sounds painless to replace if needed.

Vehicle is showing lock one, what does that mean? I called the dealer but they couldn't tell me. J

If this is showing up on the radio screen you will have to reenter the security code for the radio. If the code is not written in the owners manual you will have to take it to the dealership and the can hook it to the computer and reset the lock code. Hope this helps.
