Chrysler Java P1807 Engine Trouble Code
What is Chrysler Java P1807?
With Chrysler Java P1807, you may drive for several weeks with a malfunctioning MAF sensor, but expect decreased fuel economy and eventual stalling. Shop replacement costs $240–$400 depending on vehicle. The labour is straightforward, with most cost from the part itself.
P1807 on the Chrysler Java
Transmission-mounted speed sensors on the Chrysler Java share a ground path with the engine control module. A corroded ground point on the transmission bell housing generates electrical noise that the ECU misinterprets as a P1807 fault condition.

How to Fix Chrysler Java P1807
Diagnostic Steps:
Poor running symptoms align with MAP sensor malfunction. In some cases, a faulty MAP sensor will not trigger a code. The issue may represent separate wiring concerns requiring individual diagnosis.
Repair Solution:
Brake switch circuit concerns may involve open or shorted BPP circuits, damaged switches, or misadjustment. Verify stoplight function and follow proper self-test procedures per service manual.
Technical Notes:
P1807 DTC indicating a sensor fault does not always mean the sensor itself is bad. The issue may stem from the systems being monitored or even the sensor wiring. Proper diagnosis is essential.
