P0836 Error Code in 2004 Jeep Cherokee: Transmission Stiffness and Accelerator Responsiveness
My 2004 Jeep Cherokee exhibits a significant issue when driving in high range: the accelerator is completely unresponsive. Pressing the gas pedal results in no increase in engine RPMs. The vehicle operates normally in low range. Diagnostic trouble codes P0836, P0243, and P034
Could this be a diesel model? Fuel type may influence the symptoms. Also, did you use an OBD-II scanner or try the key-on-key-off method to retrieve codes? The key-on-key-off trick is often insufficient for accurate code reading and may not capture all faults.
