could either be a faulty heater core, or the water pump is starting to go and when you hit the gas the radiator fluid moves threwe the heater core beter
Was that the only code that caused you to replace it? Do you have it close enough to sense again.
Sensor??? A misfire is usually caused by spark plugs and wires. After that you change distributor cap(if equipped) , fuel injectors, check for proper compression.
your knock sensor could need to be replaced
Nope, the knock sensors only goal in life is to inform the engines control module to adjust the spark timing to optimize engine performance and fuel economy. the "knock" is caused by predetination which is caused by spark timing to far advanced or crappy quality fuel. check the fluid in tranny it may need to be flushed and the fluid replaced what kind of car is it?
It is caused by Bank 2 Sensor 2 oxygen sensor failing.
it can be caused by a bad alternator
The knock sensor sends a voltage pulse to the computer whenever it detects the vibrations caused by metal, such as the conditions caused by the spark knock. When the knock sensor sends a voltage pulse, the computer retards the timingin an effort to stop the spark knock.
This is water hammer and is caused by rattling pipes that are not secured down properly
The calendar
replace the computer under hood driver side i had same problem changed that and fixed..... It could also be the Crank Sensor which is located on the backside of the engine on the transmission bell housing. That caused the same problem.
p0171 and p0174 are generic codes, they could be just about anything. i got them and realized i had a vaccume leak on the hose that connected to the pcv valve. check your valves and hoses going to you intake I had a customer with this problem and it was caused by a fouled mass airflow senor. The cutomer installed the air filter backwards which caused the injectors and MAF sensor to get fouled up. Injectors werent giving enough fuel to the engine. The injectors needed flushed out and Blew the mass air flow out. I recommend the mass air flow sensor be changed out when this happens bc it will never be the same. I hope this helps some.
The knocking sound that the sensor is designed to detect is caused by uneven combustion of a lower octane gasoline than the engine is able to burn efficiently. The knock sensor signals the Electronic Control Unit and ignition timing and other engine parameters are changed to eliminate the knocking. Knocking, if allowed to continue over a long time can seriously damage the engine. --Ken
