RE: Code 4726 (12-11-2025 )Dream Big Wrote: i have the 4726 code and 1139 please help prv is good 1139 = Injector for cylinder #1 is failing. 4726 = excess fuel leakage at the rail. -- Do an injector leak-down test to see if it passes. Fix the issues until it does. info: https://rawze.com/forums/showthread.php?...3#pid75483 -- Replace the exhaust gas pressure sensor (use OEM sensor only) + clean out its passage between it and the exhaust manifold. -- If the engine has a delete program in it, then copy it out ans e-mail it to me for a review of what someone did in there. Bad programming is a plague and most people would swear nothing is wrong until it causes severe engine damage, and then its too late.
