How to Troubleshoot a Dodge Dynasty 1Check your gauges very first; they're your initially line of diagnosis, in particular for charging and cooling program concerns. A voltage gauge that reads low at idle but rises with rpm indicates a undesirable alternator (also indicated by dimming and brightening of dashboard lights). A coolant gauge that rises at low rpm indicates a negative fan (which you should be in a position to hear at idle), low coolant level, blocked coolant passages or maybe a undesirable water pump. 1 that rises below cruise indicates a radiator blockage, low coolant level or bad water pump.2Read the engine codes. The Dynasty utilizes On-board Diagnostics, Series Two (OBD-II) Professional diagnositic tools, and can self-diagnose most engine and transmission problems. Most chain auto parts stores possess a code-scanning tool that could study any active codes (these that trigger the check engine light to keep on), but will not read stored codes. You are going to have to have to take the auto to a garage to read stored codes.3Listen for any strange noises coming from the engine car diagnosis tool, and locate the source. A loud, continual squeal may well indicate a slipping belt; a quieter, additional high-pitched squeal may perhaps indicate a poor accessory-drive bearing. A tough clattering coming from the valve cover may indicate a collapsed lifter, worn out rocker arms, damaged valve spring/retainer or bad valve; a softer rapping from the fuel injectors indicates a problem there. A loud knock from deep inside the bowels of the engine indicates worn or damaged bearings.4Use a multi-meter to examine sensor output. Automotive sensor technologies circa 1990 wasn't what it's these days, and sensors are commonly some of the first things to go on these cars. Check throttle position sensor (TPS), oxygen (O2) sensors, manifold air pressure (MAP) sensor, crankshaft position sensor (CPS), knock sensor, coolant temperature sensor and transmissions fluid pressure/temperature sensor. Use your digital multi-meter to figure out in the event the sensors' voltage outputs fall under the various ranges specified in your reference book. Related articles:
