I am getting 311, 113 and 231 OBD codes in my 91 245.
113 and 231 may be related to the O2 sensor which was replaced maybe 6 months ago with a Bosch Universal sensor. I have cleaned connectors to the sensor with CRC
311 is for missing speedometer signal at the cluster or speedometer. I know the cluster is not correct for the year, it has an 87 date code on it. Is there anything I can do to correct this? I am having idle problems and idle air valve and TPS work fine and everything is clear. I get a 332 code checking TPS off idle and Bentley says I should get 334? Is this OK or is there a problem?
Thanks
Dan
