2008 honda accord. Installed rebuilt engine. Will not start and have following codes. p0118 p0102 p0113 p2649. The radiator fans come on as soon as I turn on ignition. Engine temp gauge also climbs to hot with ignition on. I checked engine temp, with and without jumper scan tool indicates -40c. I'm not getting voltage to sensor nor a ground reference. With multiple high circuit codes I assume I have a power or ground issue but can not find. I did check engine ground and it's good. Not sure where to go from here.

 

• When you said you checked engine ground, did you check G101?
• Check Under-hood Fuse No. 17 (15A).
• Check connectors to the ECM/PCM.
• Check the battery terminal connection. Also check the battery negative connection on the chassis.

P0102 and P0113 are related to the MAF/IAT combo sensor. Check the connector and sensor.
