The water pump usually throws a DME code before it fails completely.
Yes, a bad fuel pump can cause the check engine light to come on. The fuel pump is responsible for delivering fuel from the tank to the engine. If it malfunctions, it can lead to various issues, such as:
Continuing to drive with a malfunctioning water pump can lead to severe engine damage, including a blown head gasket or warped engine components. If you must drive, it's advisable to do so for a very short distance and monitor the temperature gauge closely.
A water pump should last anywhere between 60,000 and 100,000 miles. A water pump replacement costs between $400 and $800 depending on the vehicle and the difficulty involved. Parts can run from $200 to $400, with labor services similarly priced.
Since you cannot physically inspect the impeller and inside of a water pump without removing the pump, the best way to know if it is functioning properly is to visually inspect the coolant condition, test the coolant pH and protection levels, test drive the vehicle to verify normal operating temperature, and squeeze ...
One of the common signs of bad water pump functionality is overheating. The pump may not leak coolant, but the pump mechanism itself may have failed. Over time the fins of the pump can actually wear down to the point where they are no longer moving coolant.
If your car's water pump goes out, one or more warning lights may pop up on the dash. For example, you may see the low coolant warning, overheat warning, or a check engine light. The temperature gauge (if your car has one) will climb, as well.
The P0230 code indicates an issue with the fuel pump. This generic code indicates that there's an issue with the circuit between the fuel pump and the powertrain control module (PCM).
Check for diagnostic trouble codes (DTCs) with a scanner or code reader: In some cases, a faulty pump may set DTCs in your car's computer. The codes may either be directly related to the fuel pump or make reference to an air/fuel ratio problem.
A whining or groaning noise usually means that either a drive belt is loose, or the water pump pulley is bad. It may surprise your customer that a pulley could fail, but it does occasionally happen. Pulleys have been known to fail due to rust, which can cause cracking between their bolt holes.
A bad water pump typically won't prevent a car from starting directly. The water pump circulates coolant through the engine to regulate its temperature, but its failure usually results in overheating rather than preventing the car from starting.
The water pump has several gaskets that can be damaged or worn out over time. In this case, coolant may leak out and drip under the vehicle. If you notice coolant (in most cases green or red liquid) under the center front of your vehicle, it's time to check the water pump.
Test With a Fuel Pressure Gauge
In cases where the pump runs, and you're sure fuel is reaching the injectors, you should check fuel pressure. You can use a flow meter to check the fuel delivery, or the pump's output can be measured by disconnecting a fuel line and seeing how much fuel it can deliver.
Another common sign of transmission oil pump failure is strange noises coming from the transmission. This is due to lack of lubrication, which causes grinding or whining noises while driving, especially during gear shifting.
If the water pump is malfunctioning, the engine will overheat due to poor coolant circulation. A faulty water pump may not push the coolant through the engine with the force that it needs. Consequently, your engine may be starved of coolant and the temperature will rise beyond normal and into overheating.
On average, replacing a water pump can range from $400 to $1,000. Some factors that can affect the cost include the type of engine, the location of the water pump, the cost of the replacement pump, and the cost of labor to remove and replace the pump.
Take your radiator cap off and note the coolant level. idle the vehicle until it's hot enough for the fans to kick on, maybe 10-15mins depending. When they do, you can look down in your radiator and see the coolant level drop and probably see it circulating as well.
Driving with a bad water pump, especially if it's blown, is not advisable. Get a Professional Assessment: Once your vehicle is at the repair shop, have a professional mechanic assess the extent of the water pump damage and recommend the necessary repairs or replacements.
