ENGINE)
An intermittent "Check Engine" light with an intermittent Code 22 or Code 34 may be the result of a shorted wire harness at the generator bracket (2.5
Liter engines).
The MAP and TPS wire harness runs through that area and may become abraded by the bracket.
The condition can be confirmed by noting a voltage drop to zero volts when the harness shorts out. A repair should be made to protect the wires from
further abrasion.
