2015年3月11日 · I've got a P1188 code problem (fuel control (trim) bank 1 sensor 1). I've searched and read through many threads on this problem both on this forum and others but can't seem to sort it out and could use some more help. below is what I did based on the others posts I've read and then erased the...

2012年10月11日 · P1188 and P1189 mean FUEL CONTROL MALFUNCTION, BANK 1 & BANK 2, respectively. Fuyel control can be rich or lean, or it can have a malfunction -- which logic says is both rich and lean at different times. My car had these codes, and the MAF (not mas, by the way) was the problem.

2010年6月23日 · For some time, I have had these codes with the SES light on: P1188 P1189 Usually, but not always, with one or more of these codes: P1250 (especially this one) P0170 (P0171 on M54 & M56 engines) P0173 (P0174 on M54 & M56 engines) P0150 P0130 Freeze frame data on my scanner...

2010年10月20日 · Finally solved engine code issue..P0170,P0173,P1188,P1189 Well I've had these codes for an year, I finally solved it. P0170,P0173, P1188,P1189 they are all related to fuel system. So I thought the problem was somewhere in fuel system, so I've replaced fuel pump, fuel filter, used seafoam, fuel system cleaner but nothing solved the problem.

2011年2月8日 · The only code left is P1188. The van still will not downshift, has low power on hills but no smoke and 25-28 on the MAP scangauge at full throttle.. while LOD hovers at 65-73.

2011年1月7日 · P1188 and P1189 are Fuel Control codes, similar in meaning to P0170 and P0173, Fuel Trim Malfunction. P1188 and P0170 are Bank 1, the others are Bank 2. P0335 is the Crank Position Sensor, and is probably the one that made the car run poorly. I do not think the O2s are your problem.

2013年10月26日 · I have a 1999 323I and today the check engine light came on and the scanner says its a p1188...I googled it but most everyone with the p1188 code had the p1189 code pop up at the same time so I am confused about what the p1188 code means and how to go about fixing it.. some said it was an 02...

2013年3月2日 · I managed to take care of the code P0301 due to bad 1st cylinder ignition coil - Thank you everyone from this great forum!! From my research, P0170, P0173, P1188, and P1189 are all have to do with the crank case vent hose.. Am I right or wishful thinking? The car will stumble, the RPM jolt up...

2010年10月14日 · Back to the original post, my 1999 Z3 2.5 is throwing the exact same three codes. This original post was from 2010. What was the problem and solution? Anybody else suffering with P1188, P1189, and P1250? Sent from BimmerApp mobile app
