Not quite the weekend off as planned, Jon had to return to Spilsby to see neighbours Denis and David, this morning to investigate issues with a couple of Lambda sensors, that we fitted back in March, causing the malfunction indicator lamp (MIL) to come on, on both cars.
Denis had reported that his stepspeed was running lumpy since fitting the sensor at the beginning of March, and also David’s car saw the amber light come back on once or twice. Jon returned with replacement Lambda sensors and in Denis’s case it was a faulty part. The lambda sensor was replaced and in addition we installed a k-maps remap, (as we’re now a franchise for them) with an MIL eliminator, just to make sure the problem doesn’t reoccur. Although, if the issue should return the ECU will now log the problem, but it won’t put the amber light on. That cured car No. 1 of today.
Car No 2, David’s TF 135, on checking the Lambda sensor condition it was found to be working perfectly well in the way of its use of the heating element, also the voltages were varying in the way of the sensor readings, and the condition was classed as ‘ok’. Finally it was logging; rich, normal and lean and switching between those perfectly well. The code that the ECU had logged when putting the light on was P0420, which means that the catalytic converter was failing, most likely due to saturation from the previous sensor, causing over fueling. The catalytic converter ideally should be replaced, as it the original, but the addition of cataclean may help with this issue, if not then a new cat will be required.
A bit of a long day for Jon, with a visit first thing this morning in Hull to have a set of Falkens fitted to Andy’s cars’ wheels that he will be collecting next week.
I had a day off to go wedding outfit shopping. Very strange being in clean non work clothes! Poor Jon’s a bit worn out, but we definitely have a proper day off tomorrow. 😀
