Saab 93 2.0 T Auto 2001 - Intermittent non start P1640 #

Posted by Chris Jarvis on June 24, 2009, 4:56 pm

Year of Manufacture *: 2001
Engine Code or Type *: 2000 cc Turbo Auto

Intermittent none start

Car will not crank

1 Fault code logged P1640 - Power loss to ecu pin 1

Swoppped main relay, and gear lock out relay

Fault can occur once or several times a day no repeat pattern

Checked ecu connections, fuse box connections

Very hard with being so intermittent

When fault occured AA can bridge starter relay and it will start stright away

Does anybody have a wiring diagram or is there any known issues with this car

Many Thanks

Chris

Sorry Chaps

The car is a 2001 Saab 93 2.0 Petrol Turbo Automatic

The fault is intermitent none crank situation, immobilzer light goes out but no crank.

Customer has tried both keys

We have swopped relays around main, fuel, ignition, it has previousley had an ignition cassette,

The Only DTC Logged is P1640

Thanks Dave

Very helpful

Checked wiring, volt drop check and pin condition

Car starts every time for us at the moment, does not appear to be temperature related

Will keep trying and post results

Thanks

Chris
