Car is a 98 Disco. Has been running fine. No problems. I got my Ultra Gauge today. Hooked it up this afternoon. The car has an o2 sensor out so that check engine light was on. I was going through the menu options and notice it had a clear engine light option on there. I thought cool! And I cleared the o2 code (ive done this a few times with a pocket scanner) I wish I wouldn't have done that. Drove the rover to a local bar, drove fine. Met a friend for a beer, came back out. Tried to start it and it starts, putters and dies. Tried it again...same thing. Unplugged the Ultra Gauge and same thing. Plugged it back in and a new pending code came up. P1178: Maximum Positive AMFR correction fault. I unplugged the battery for 5 minutes. Put the terminal back on. Same result. What the heck did I do? How do I fix it?
MAF could be unplugged. From RAVE shop manual,SFI fuel system:
As there is no default strategy, failure will result in the
engine starting, and dying when it reaches 550
rev/min, when the ECM detects no MAF Sensor
signal. The fault is indicated by illumination of the
malfunction indicator light (MIL) on North American
I agree with Spike. Also, you "NEVER" disconnect the battery to clear a code, all you accomplish is a clearing of the memories from many of the ECU's that then must be relearned over the next day or two of driving, so leave the battery alone.
