2001 Pontiac Grand Am GT P0135 Fault Code: Diagnosis and PCM Programming Costs
I'm currently experiencing the same issue with my 2000 Chevrolet Impala, and I'm considering replacing the Powertrain Control Module (PCM) to resolve the P0135 fault code. Before proceeding, I want to understand the programming requirements—was the PCM programmed by a specific service provider? What was the cost involved, and would they assist with installation if I ship the unit to them? I’m aware that local garages charge up to $700 for this work, which seems excessive. I plan to contact several vendors tomorrow to compare pricing. Any insights or recommendations on reliable PCM programming services—especially those offering remote support—would be greatly appreciated. If possible, please share your experience or contact details directly via email at damagetone@aim.com. Thank you in advance for any help or advice.
