What Is The Code P0234 Ford Escape?
The P0234 trouble code that an OBD scanner generates if the ECM (Engine Control Module) gets any irregular boost pressure signals lesser than 4PSI and more than 17PSI for above five seconds.
Indeed, it’s an overboost condition of the Turbocharge or Supercharge. The ECM creates and activates this code for higher or lower boost pressure than the normal value. Getting the lower boost pressure for the Ford Escape is common, and most users have experienced this issue.
The carburetor can’t hold the pressure inside it. So, when it gets a higher or lower boost pressure, it causes issues with the cylinder chamber. As a result, your vehicle can face problems like loose brakes.
The situation is very critical when the engine goes through this issue. Even it can explode deadly to harm the engine itself and the driver. Hence, you must instantly respond to the P0234 Ford Escape boost pressure sensor error's symptoms.

Turbocharger Isn’t Working Properly/Damaged
The turbocharger in a vehicle ensures essential gas to the related components like the engine. It compresses the air and boosts its pressure intensely. However, if it produces extra pressure than the expected value, the turbocharger can’t manage it and generates the error code P0234 Ford Escape 2016.
How To Fix It
Repairing the turbocharger is possible if you do it at the beginning of the issue and if its damage level isn’t severe. Otherwise, you’ll get the best result by replacing the defective turbocharger.
Defective Control Valve Solenoid
Usually, control valves are likely to regulate gases coming out from the exhaust and inlet. When there is a higher pressure, the valves don’t work and get damaged after a while.
The car's monitoring system, ECM, records this disparity and indicates the issue with the P0234 Ford Escape 2013 trouble code. The blocked valves become damaged and irregular to control the pressure.
How To Fix It
Check the valves first. If they’re clogged for any reason, you can repair them. Turning the engine off and decreasing the pressure level slowly should fix the issue. However, completely damaged valves are not repairable. A 2015 Ford Escape wastegate solenoid replacement will help you resolve the problem.
Congested Wastegate Pipe
The Ford Escape has wastegate pipes to overcome potential failures, like the P0234. The responsibility of these pipes is to remove gases from the turbocharger to maintain a normal pressure level in the engine.
But these pipes can be congested or leakage to technical glitches. As a result, they don’t work correctly to take the gases out to keep the pressure level standard. Then, the system generates the error code P0234 Ford Escape with symptoms like gasket sounds.
How To Fix It
When you need to perform the P0234 Ford Escape fix, we suggest replacing the damaged hose pipes as they’re not much costlier. So, fix the problem as soon as possible to get your vehicle in its actual state by subsiding the P0234 trouble code.
Wrong Wastegate Tuning
The wastegate actuator is helpful in controlling pressure boosting. There are springs and other components to regulate the wastegate shutting down and opening. If they’re not tuned correctly, the gases pass through different ways, like the turbocharger and engine inside.
How To Fix It
Try to adjust the wastegate properly. If there are any other issues, such as clogged pipes, fix them accordingly. When you fail to fix those ways, replacing the damaged wastegate pipe is the ultimate solution.
Faulty Sensors Wiring & Connection
The turbocharger in your car comes with some electrical components connected with wires. A defective sensor wiring with a loose or open connection may trigger the P0234 error code.
How To Fix It
You can guess the solution as you know the reason for the issue. Check the wires and their connections. Reconnect them and tighten the wires if there are loose or open connections.
Faulty Boost/BARO/MAP sensors
Sensors transmit various signals between turbochargers and other components linked with the monitoring system. When one of the sensors gets damaged, the communication system breaks down. As a result, the ECM records this issue and produces the P0234 code.
How To Fix It
Simply replacing the defective sensor will resolve the problem. You should do this replacement task under a professional auto mechanic.
Twisted Actuator Rod
Most users get their actuator rods twisted for higher pressure and power. A bent actuator stick is another common reason for getting the P0234 error code.
How To Fix It
Flattening the bent actuator rod should fix the issue. If not, replace it with the new actuator rod.
How Much Does It Cost To Replace The Turbocharger?
P0234 Ford Escape costs for its Turbocharger replacement between $1674 and $1873. You can save hundreds of bucks by performing this replacement task independently. But if you want to do it yourself, you must have enough technical and practical skills with essential tools.
Besides, the P0234 repair cost for the sensors is between $88 and $151. Here, the sensors’ cost is around $44 and labor $35. However, the cost may vary depending on factors like the part’s brand, the applicable taxes, and relevant fees.
How To Replace The Turbocharger – Step-By-Step Instructions

Frequently Asked Questions – FAQs
How To Fix P0234 Error Code On The Ford Escape?
When you get the P0234 trouble code, you must take the necessary actions immediately. The major reasons for the issue are dented turbocharger, solenoid valve, and wastegate pipes. So, check them closely to find the damages and fix them appropriately. The issue may require complete replacement with the new parts depending on the severity of the damage. Sometimes, some simple repair tasks resolve the problem.
What’s The Lifespan Of The Turbocharger On The Ford Escape?
The normal life expectancy of the turbocharger is about 100,000 to 125,000 miles. However, depending on your driving frequency and conditions, such as extreme hot and cold weather, it may be faulty.
Is It OK To Drive A Car With The P0234 Error Code?
It’s highly prohibited to drive your vehicle with the P0234 code. It’s because you must not like to ride with explosives that can blast anytime. This warning code appears when there is extra pressure in the engine for a damaged turbocharger or any other component’s failure. When the number of gas increases in the engine, it can explode after a while. So, as the P0234 is one of the highest prioritizing error codes, stop driving immediately and fix it without delay.
Why Is Extreme Boost Pressure Dangerous?
Boosting too much pressure in the engine is risky as it can damage the head gasket. Also, it’s liable for decreasing the fuel economy. Moreover, excessive pressure can make the engine overheat. And all those things may result in damaging the entire engine.
What’s The Normal Value Of The Turbo Boost Pressure?
The ideal ratio of drive and the boost pressure is 1:1, which can fluctuate for various driving and engine factors. It’s OK if the driving pressure is slightly higher than the boost pressure. But if the difference in these two pressures becomes double one another, for example, drive pressure is 65PSI while boost pressure is 35PSI, it can be a dangerous engine situation.
The Bottom Line
The situation isn't out of control when you first get the P0234 Ford Escape with symptoms. Some simple repairs or inexpensive parts replacement will fix the issue. And you’re all set to drive your car without any risk.
But taking the warning signs and the code lightly without fixing them early will cost you thousands. It’s because extreme boost pressure conditions can damage the engine with related components.
