Yeah , P1234 or B1234 An it want or won't start . You need factory service repair info.to know what this is . For all codes there is a diagnostic trouble shooting procedure . Without this info your best bet ,have it towed to a qualified repair shop. 4WD - 2WD . If P - powertrain code factory info doesn't show this code . What cheap code reader are you using . It's not telling you the correct code . Cheap code readers will do this. Your best bet , take it to a qualified repair shop.
