Re: 98 Tahoe computer?

The input from the CMP to the VCM goes thru connector C1 (blue) pins 3 & 8.

Pin 3 is BRN/WHT wire and pin 8 is PNK/BLK.

The diagnostic aids for P0341 point to possible electromagnetic interference from after market equipment, harness routed too close to the High Voltage side of the dist, harness routed too close to relays or solenoids and/or shorted or open wiring in the circuit.

With the engine running, move the engine harness at various locations. If the RPM's change while doing this you may have found the problem area.
