A Kia Carens with 1.6 liter engine keeps generating an oxygen sensor related code that the fuel mixture was too rich. Resetting the error and driving the car would set the error code again. Several components were replaced, even the Electronic Control Module (ECM), but the error kept coming back. Diagnosing using a automotive labscope revealed the cause of the problem. tiepie@tiepie.nl (TiePie engineering) Wed, 01 Feb 2012 00:00:00 +0000 news-en-1653 Automotive http://www.tiepie.com/en/news/item/1587 A new automotive application article about a Citroën Xantia refusing to start is added to the Automotive section of the website. A 1999 Citroën Xantia had a new starter motor fitted, after which it would not run anymore. While cranking it would fire briefly and then die. The car’s battery had been disconnected for the starter motor job. A crankshaft sensor code was logged and thus the crankshaft sensor was replaced, regardless of the good signal. Later the ECM was replaced all with no positive results. The question was if the immobilizer could have reset itself by disconnecting the battery. Proper measuring revealed what the real problem was. tiepie@tiepie.nl (TiePie engineering) Mon, 12 Dec 2011 00:00:00 +0000 news-en-1587 Automotive http://www.tiepie.com/en/news/item/1520 A new automotive application article about a stuttering Ford Fiesta is added to the Automotive section of the website. When trouble shooting intermittent problems, a good automotive oscilloscope is indispensable. A Ford Fiesta with J6B engine was suffering occasional stuttering. The shop it was brought to did not have an oscilloscope, so they could not easily locate the source of the problem. They did replace some components, but the problem remained. Using an automotive diagnostic oscilloscope, the problem was soon found. tiepie@tiepie.nl (TiePie engineering) Wed, 30 Nov 2011 00:00:00 +0000 news-en-1520 Automotive http://www.tiepie.com/en/news/item/1475 A new automotive application article about a hesitantly Renault Megane is added to the Automotive section of the website. Intermittent problems in cars can give garages a hard time, especially when their only diagnosis device is a fault code scanner and no codes are stored in the car. A garage deals with a 1998 Renault Megane 1.6 L with K7M engine with a dual fuel system, both petrol and LPG. Every now and then, the engine hesitates, both on petrol and on LPG. The garage performs some measurements and replaces the ECM, to no avail. Using an automotive oscilloscope the search was continued and the culprit was found. tiepie@tiepie.nl (TiePie engineering) Wed, 22 Jun 2011 00:00:00 +0000 news-en-1475 Automotive http://www.tiepie.com/en/news/item/1458 A new automotive application article about a Ford Mondeo with a fuel pump issue is added to the Automotive section of the website. In modern cars with sophisticated and complex components, trouble shooting requires powerful tools. A Ford Mondeo 2.0 TDdi would no longer run. Fearing that wrong fuel was tanked, the tank was emptied and the fuel system cleaned. The proper fuel was added but the engine would still not start. Since wrong fuel was used, damage to the fuel pump was suspected. The pump was replaced, the engine replaced and the pump replaced once more, to no avail. Diagnosing using an automotive labscope showed that a seemingly innocent component caused the problem. tiepie@tiepie.nl (TiePie engineering) Mon, 06 Jun 2011 00:00:00 +0000 news-en-1458 Automotive http://www.tiepie.com/en/news/item/1442 A new automotive application article about a troublesome Volvo XC70 is added to the Automotive section of the website. A Volvo XC70 had serious engine related drivability problems. The engine lacked power, would hold back and even stall. Error codes indicated problems in two different areas. Replacing components did not improve things. Proper measuring with an automotive diagnosis oscilloscope revealed two independent problems. Fixing these solved all problems. tiepie@tiepie.nl (TiePie engineering) Wed, 18 May 2011 00:00:00 +0000 news-en-1442 Automotive http://www.tiepie.com/en/news/item/1436 A new automotive application article about a Honda Jazz that holds back and stalls is added to the Automotive section of the website. A 2006 Honda Jazz with L13A i-DSI engine occasionally holds back and sometimes even stops. No error codes were stored in the car. Several components have been replaced or swapped with an other car. A lot was driven in the car with a scanner hooked up to monitor the "live data" to find an anomaly in sensor or actuator data. Nothing showed up. Only after diagnosing with a good automotive diagnose oscilloscope, the cause of the problems was revealed. tiepie@tiepie.nl (TiePie engineering) Wed, 20 Apr 2011 00:00:00 +0000 news-en-1436 Automotive http://www.tiepie.com/en/news/item/1181 A Golf 4 turbo GTI was having serious problems with accelerating. Accelerating from 0 to 80 km per hour would take approximately 16 seconds, which is far too long for this car. Apart from the lack of power, the engine would hold back every half second and produce a lot of explosions in the exhaust. Based on an assumption, measuring with an automotive oscilloscope was started, but it lead to no solution. When the assumption was ignored and measuring with the automotive labscope was started at the basics, the cause was found in a different area than initially was thought. tiepie@tiepie.nl (TiePie engineering) Thu, 26 Aug 2010 00:00:00 +0000 news-en-1181 Automotive http://www.tiepie.com/en/news/item/316 An Opel Agila with Z 12 XEP engine runs bad and generates lots of throttle related error codes. The garage replaces the throttle body, throttle position sensors, the ECM and even a part of the wiring harness, to no avail. When measuring the vital signals with an automotive oscilloscope, the cause of the problems is revealed. tiepie@tiepie.nl (TiePie engineering) Fri, 07 May 2010 00:00:00 +0000 news-en-316 Automotive http://www.tiepie.com/en/news/item/314 The engine (B205E) of a 1999 Saab 9-5 intermittently shows a "hiccup" but then continues to run properly. Over time, the problem became worse and and at some point, the car would not start for 20 minutes. The owner consulted a garage that concluded that the special Direct Ignition cassette needed replacement. Unfortunately that did not solve the problem. Time to start measuring properly, using an automotive oscilloscope. tiepie@tiepie.nl (TiePie engineering) Mon, 15 Feb 2010 00:00:00 +0000 news-en-314 Automotive http://www.tiepie.com/en/news/item/310 A Renault Kangoo with E7J 780 engine is suffering a bad start: it starts but stalls within 2 seconds. Several garages replace several parts but none can fix the problem. All signals appear OK, but are they? Thorough measuring with an automotive oscilloscope and analyzing the signals reveal the surprising culprit. tiepie@tiepie.nl (TiePie engineering) Wed, 23 Dec 2009 00:00:00 +0000 news-en-310 Automotive http://www.tiepie.com/en/news/item/307 A Peugeot 205 with G6 motor management system showed serious problems during acceleration. While accelerating, the engine would constantly hold back. The problem seemed worse during strong acceleration. The garage checked the fault code memory but found no codes. They even drove the car while monitoring the data stream from the Engine Control Module (ECM). During the holding back no strange things were found in the data stream. After replacing spark plugs and cables, DIS coil, camshaft sensor and throttle body, the car still showed the problem. Where to look now? tiepie@tiepie.nl (TiePie engineering) Mon, 30 Nov 2009 00:00:00 +0000 news-en-307 Automotive http://www.tiepie.com/en/news/item/304 tiepie@tiepie.nl (TiePie engineering) Mon, 19 Oct 2009 00:00:00 +0000 news-en-304 Automotive http://www.tiepie.com/en/news/item/299 tiepie@tiepie.nl (TiePie engineering) Fri, 25 Sep 2009 00:00:00 +0000 news-en-299 Automotive http://www.tiepie.com/en/news/item/297 A new Automotive application article about a badly starting Jeep Cherokee is added to the Automotive section of the website. It describes A Jeep Cherokee that was diagnosed to need a new engine. Proper measuring with the right equipment proved otherwise. tiepie@tiepie.nl (TiePie engineering) Tue, 30 Jun 2009 00:00:00 +0000 news-en-297 Automotive
