For the last day or so my '96 ZJ 6 cyl. Laredo has been running rough and stalling. It'll smooth out for 5 miles or so then start stalling again. Just today the "Check Engine" light came on so I did the on-off-on-off-on-off-on thing with the ignition switch and got the following error codes.
Code Description
11 No crank reference signal detected during engine cranking. Intermittent loss of either camshaft or crankshaft position sensor. CKP sensor target windows have too much variation.12 Direct battery input to PCM was disconnected within the last 50 Key-on cycles. ( I had the battery disconnected over the weekend so I understand this one)
14 MAP sensor input above or below acceptable voltage. 5 volt output to MAP sensor open.43 Peak primary circuit current not achieved with maximum dwell time.
43 Misfire detected in one or more cylinders 1 thru 6. (4 and 6 cyls.)The "no crank reference signal" "MAP sensor below acceptable voltage" and "Peak circuit current not achieved" leave me scratching my head.
Can anyone tell me what these codes are indicating and what i can do to test for and correct these issues?
Best Regards,
Marcel
