Ways to Troubleshoot a Dodge Dynasty 1Check your gauges very first; they are your initially line of diagnosis, in particular for charging and cooling program difficulties. A voltage gauge that reads low at idle but rises with rpm indicates a negative alternator (also indicated by dimming and brightening of dashboard lights). A coolant gauge that rises at low rpm indicates a negative fan (which you ought to be able to hear at idle), low coolant level, blocked coolant passages or perhaps a bad water pump.
One that rises below cruise indicates a radiator blockage Vehicle Diagnostic equipment, low coolant level or bad water pump.2Read the engine codes. The Dynasty utilizes On-board Diagnostics, Series Two (OBD-II), and may self-diagnose most engine and transmission difficulties. Most chain auto parts shops have a code-scanning tool which will study any active codes (these that result in the check engine light to keep on), but will not study stored codes. You will require to take the car or truck to a garage to read stored codes.3Listen for any strange noises coming from the engine, and locate the supply. A loud, continual squeal may well indicate a slipping belt; a quieter, extra high-pitched squeal may well indicate a negative accessory-drive bearing.
A hard clattering coming from the valve cover may possibly indicate a collapsed lifter, worn out rocker arms, damaged valve spring/retainer or bad valve; a softer rapping from the fuel injectors indicates an issue there. A loud knock from deep in the bowels in the engine indicates worn or damaged bearings.4Use a multi-meter to check sensor output. Automotive sensor technologies circa 1990 wasn't what it can be today, and sensors are generally several of the 1st factors to go on these vehicles. Verify 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 identify if the sensors' voltage outputs fall below the numerous ranges specified within your reference book car diagnostic tool.
