Subject: Repeat DTC P0606 and P1780 Setting

Models: 2000-2005 Saturn L series with L81 V6 The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern:
A technician may find codes P0606 and P1780 setting. They may state that they are not able to duplicate the concern. Tech may state that when the customer is driving they report a sudden loss of power, then no throttle response, and the warning indicators come on. Tech may also state that the ECM and MAF were replaced with no change.
Recommendation/Instructions:
These codes will set if the wrong MAF was installed on the vehicle previously. This being an intermittent code the MAF may work without any concerns initially. The retailer may not be aware of 2 different part number MAF's for 2000-05 L series with L81. Compounding this is the reman sticker may fall off and GM does not cross reference the Bosch part number to theirs. Any time these codes are setting have technician verify the correct MAF is installed using the reference below
The part numbers are:
2000-03 90528435 Last 3 of Bosch # 184 (important because the reman sticker may be missing)

Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
