Note: - This is NOT the element, rather it appears to be a guard to stop you touching it. The same sensor after cleaning with a can of electrical cleaner.Ĭlose-up of the 'hot wire' element protector, again you can see the baked on dirt. The MAF sensor and (I believe) the intake air temperature sensor, removed from the MAF housing.Ī close-up of the thermistor which sends intake temperature information to the ECU. In the case of my Volvo, it was hesitation off-idle and general bad behaviour and unresponsiveness in the lower rev range. This dirt can settle and bake onto the MAF sensors 'hot wire' or 'hot film' element and cause the sensor to give an incorrect reading.
#GENDAN ENGINECHECK PLUS#
During which the O2 sensor, Mass Airflow sensor (MAF) or Manifold Air Pressure (MAP) sensor (plus others) trim the amount of fuel to give the best possible fuel delivery (as decided by the manufacturer!)īank 1? That applies to Vee or boxer engines, where 'Bank 1' is the one where the number 1 spark plus is, in an in-line five-pot car like mine, you only have 'bank 1'.ĭespite the best efforts of the cars air filter, a certain amount of dirt will still get into the air intake system.

The engine uses this map exclusively when in 'open loop' mode, such as accelerating flat out.ĭuring cruising conditions (pottling along nicely) 'closed loop' is used. Modern electronic (rather than mechanical) fuel injected vehicles use a 'map' to decide how much fuel to supply to the engine for any given load, speed, temperature etc. The last value is an important one, 'closed loop' indicates that the ECU is accepting feedback from the O2 sensor, the one prior to the catalytic converter. Long Term Fuel Trim Bank 1 = 3.91% - After a period of time, the short-term fuel trim adjustment is passed over to the long term fuel trim parameter. Short Term Fuel Trim Bank 1 = -9.38% - The ECU has reduced the amount of fuel it is supplying by 9.38% as the engine seems to be running too rich. "P2188 - System Too Rich at Idle (Bank 1)"Ĭalculated load = 23.14% - The engine is at idle and just pulling its own weight, so to speak.Ĭoolant Temperature = 91 degrees celsius - The engine was at normal operating temperature. The above image shows the opening screen and the stored error code.
#GENDAN ENGINECHECK HOW TO#
The next step was learning how to interpret the readings.
#GENDAN ENGINECHECK SOFTWARE#
"Measure twice - cut once." (Well used woodworking term).Īlthough I had a suitable connector to fit the Volvo's ODB socket, it was obvious that the software would need to be replaced.Ī quick e-mail to Gendan and I confirmed that their 'Engine Check Pro' software would work with the Volvo S60's electronics.ĭownloading and installing it took no time at all and the e-mail with the code arrived on a Saturday morning, despite me not sending the payment until Friday evening (great service). Note that mine was cheaper as it came with a light-weight version of the software shown. The hardware used with this is an Elmscan 5 USB interface. The Vauxhall Vectra used an older software program called 'Vauxcheck' from Gendan. It taught me an awful lot about fuel injection system status (I already knew the basics of how it worked), taught me what looks right and what does not and taught me once again (see the Renault page) that you can have all the diagnostic tools in the world, but if you don't know how to interpret the data, they are worth 'Jack s&%*'.Īfter the expensive experience of having a dealer read an engine fault code on my Vauxhall ("That will be 70 pounds sterling, sir.") I had decided to equip myself with the ability to do it myself. This web page details the path I took to locating the problem. The problem had made the car all but un-sellable as a trade-in, since no dealer wanted to take on board the risk of an expensive fix for its new owner. So now it was up to me to sort out the issue. I knew the history of this car as for the last four years it has been parked next door! The previous owner had taken the car to the garage on a regular basis, on at least of half a dozen occasions, with no success.
