If there is no signal detected, then a visual inspection of the crankshaft and related components is necessary. What can I do to correct this issue? The computer ran the mixture to the rich limit of programming, but the O2 sensor still indicated a lean condition. So you should chech it on our car models. All stored codes will be erased if the battery is disconnected for 15 minutes, but a fault code 12 will be set when the battery is reconnected. The Check engine light will flash many short blinks.
The typical aluminum head swells most in the middle, which can crush the head gasket if the head gets too hot. The vehicle service manual should be consulted for more information on possible causes of the fault, along with required testing. Because of this, it is recommended that you deal with a P1103 trouble code as soon as possible. YourMechanic offers certified mobile mechanics who will come to your home or office to diagnose and repair your vehicle. Indicates that the ignition coil's peak primary circuit current is not achieved with the maximum dwell time. Computer is indicating that the battery voltage is not being regulated. What causes the P0378 code? Thermal stress can distort the head and make it swell in areas that are hottest like those between exhaust valves in adjoining cylinders, and areas that have restricted coolant flow like the narrow area that separates the cylinders.
I also replaced the ignition switch and both camshaft intake and exhaust solenoids. Another common mistake with the P0378 code is automatically replacing the crankshaft, camshaft, or distributor sensors, rather than checking for mechanical distributor failure or other issues. Ford Festiva Engine Specifications: Engine Type : Multi-Cylinder Engine Cylinder Type : Opposed Cylinder Engine Engine Air Intake Process : Supercharged Engine Your Ford Festiva engine control system detects a problem, the computer stores the diagnostic trouble code P0378 in its memory. If this is your first visit, be sure to check out the helpful and click to sign up. Sometimes it may prevent a true user from registering. Voltage out of range at transmission temperature sensor input.
This causes the ignition coil to provide a spark and the injector to inject fuel into each cylinder at the right time. Once registered please introduce yourself. In addition to repairing and replacing items, the mechanic should check for any loose wiring and connectors. Not all fault codes are stored in memory. Check coolant level, radiator cap, temperature sensor, and thermostat. Also, no significant change in battery voltage was detected during a test of the generator output.
The other two codes I believe you can ignore. Open or short in the transmission overdrive solenoid circuit. If either sensor isn't working correctly, the car will run rough and the engine will be less efficient. I noticed a good while back that someone had removed them. What repairs can fix the P1103 code? The mechanic should be careful when removing the sensor so as not to damage the connecting wiring, which is delicate. Another consequence of P0378 Ford Festiva engine overheating may be a blown head gasket.
In order to address a P0378 code, there are a few repairs that a mechanic may choose to perform. The light will blink the number of the first digit, pause, and blink the number of the second digit. The O2 sensor signal should fluctuate under normal conditions. I figure with all the people looking for error code meanings you guys might find this useful. When the engine is started, the check engine light should illuminate for 3 seconds as a bulb test. The technician should repair or replace any components that are faulty. The light could mean a costly problem, like a bad catalytic converter, or it could be something minor, like a loose gas cap.
If your vehicle is an older model with a non-electronic Ignition System Or Misfire, you can check the distributor cap to see whether the spark is getting from there to the coil and on to the spark plugs. I recently put in a new throttle body and I still get reduced power and traction control warnings. The mechanic is looking for any damaged, loose, or faulty wiring, connectors, or components when doing this inspection. The fault code detection system is probably the same for both models. Common mistakes when diagnosing the P0378 code When diagnosing the P0378 code, a common mistake is forgetting to clear the code and do a road test after performing each potential solution.
By replicating the moment of failure, a mechanic may be able to discover the problem much faster. This step should be done after each repair, to help narrow down the cause faster. A shorted battery cell can also trigger this fault. What repairs can fix the P0378 code? The total number of blinks equals the code number. Faulty ignition components, high or low fuel pressure, or leaking injectors can set this fault. The reduced fuel efficiency also leads to more costs when putting fuel into the vehicle. But in many cases, it means at minimum that you'll be visiting the car dealer to locate the malfunction and get the light turned off.
What causes the P1103 code?. When any emissions related fault is detected, all electrical connectors and vacuum and fuel hoses should be inspected for proper connection, abrasion, etc. Many components may interact to to unbalance the emission control system and set seemingly unrelated fault codes. The 5 volt output signal is not reaching the required voltage level. P0378 Engine Diagnostic Code For 2003 Saturn Vue P0378 engine code for 2003 Saturn Vue provides below are generic codes that may not apply to all vehicles. If more than one code is stored, the Check engine light will flash the codes in sequence lowest to highest with a pause between each code. Check and repair the circuits for these, first.
