Strange codes on 98 cherokee
My 98 5.9 grand cherokee started acting odd yesterday. Occasionally,
from a stop it would be real sluggish about taking off and sounded a bit odd...almost like it wasn't getting enough gas. Then it drove ok for a while, shut it off and started it back up. CE light was on so I pulled the codes. I got these: PO726 The PCM has detected that the voltage signal from the engine speed input is out of range for the current engine operating conditions. And: P1281 Injection control pressure out of range high. Any ideas? Never came acroos anything that involved before, usually simple stuff that I can diagnose right away, but I'm kind of aprehensive about driving it without knowing what's going on. Any help is GREATLY appreciated. TIA Mikhail |
