I have a 2004 pt crusier and engine code P0572 came up and I can't find that code anywhere. What is the problem and the fix ?
Trouble Code: P0572
Brake Switch Signal No. 1 Circuit Low
Trouble Code Conditions:Ignition is on. When PCM recognizes that brake
switch is mechanically stuck in the low/on position, a DTC will set.
Three global good trips are necessary to turn off MIL.
Possible Causes:
* Brake switch signal circuit is shorted to ground
* BS No. 2 signal open
* Brake switch is damaged or has failed
* PCM has failed
i would check the brake switch first located under dash and when brake is pushed it hits switch turn ignition on and test the wires if all hot then switch is bad, other wise there is a short or bad pcm and these are not easy fixes requires knowledge of car wiring and diagnostic tools/computer
The easiest fix for a P0572 on a PT Cruiser is to replace the brake light switch. It's fairly easy to reach in order to remove the plug/connector, rotate the switch assembly off of the brake pedal hardware as it is keyed to be able to stay in place without any bolts or screws. Once removed, install a compatible replacement part. Mopar and aftermarket OEM replacements are $15-$30. Mopar Part # W0133-1675644-MPR Brake Light Switch $28 on Amazon as of May 2019
