Hi,
When the failsafe light comes on the PCM has detected a fault and goes
into a restricted mode to prevent damage to the engine and transmission.
It can be a brake switch, accelerator pedal problem or possibly a fault
with the electronic throttle.
As you have already scanned and got 1576,this code is for the pedal position sensors. The usuall cause is the accelerator pedal itself as all the sensors are internal in the pedal. The cost of the part is around $475.The pedal is easy to replace as you need to remove two 10mm nuts and one wire connector.
Let me know,if needed further assistance.
Kindly accept my solution.
Thanks for using ' Fixya ' and have a nice day!!.
P1576 = CAN data bus, Accelerator Pedal Position (APP) sensor - communication malfunction. Probable cause: Wiring, APP sensor.
CAN = Controller Area Network
It's not bad Throttle Position (TP) sensor in your case.
First time check out the APP sensor wiring. If everything is all right replace the APP sensor.
Good Luck!
Hi, the code 1576 means Brake Booster Vacuum Sensor circuit voltage high..
Fail safe engine mode is caused by a stopped up throttle body. Do not clean the throttle body since it has a protective coating to help keep deposits from accumulating. You can clean the throttle body as long as you use ONLY throttle body cleaner that states it is safe to use with a protective coating. The butterfly valve in the throttle body will actually stick not allowing air to flow into the manifold causing failsafe engine mode to kick in reducing the amount of power your engine will produce. To solve the issue just clean out your throttle body, it will cost you around $5 dollars and take 1 hour of your time.

OBD code: 1576 is generated. Also, displays "FAILSAFE ENGINE MODE" This happens when the throttle is released, and the engine looses power. Experienced about two weeks ago while driving to Boston from JFK airport, but I got the car home. I was able to place into NEUTRAL, turn off the key and re-start the motor, and it was OK for awhile. I removed the throttle body, and had it rebuilt; the place that did the work said that it was in fact bad, and the gave me a lifetime guarantee on the work. Had to replace some hoses that were damaged during the throttle body removal / replacement. Got it all put back together yesterday, drove it to the store, on the way home that FAILSAFE MODE came back on and the car died. The throttle position sensor was not replaced as part of the repair, so that is still suspect. Any other ideas? What else do I need to check? If I replace the TPS, is there anything else I need to do? Thanks.
AS I said, the TB was removed and rebuilt.All the information I find indicates 1576 is related to pedal position error.
Did you read my original message all the way through?
Please advise
OK, I was mistaken, someone else responded that it was a Vacuum assist problem..
The APP sensor is located where?
And thanks!
Thanks! I will get the part and have it replaced this weekend.
