Word power found in car manuals, dashboard buttons, technical specifications, and even legal documents. But what does it mean in Russian in each specific case? Errors in translation can lead to improper operation of equipment, breakdowns, or even fines. For example, the inscription Power Steering on the steering column - this is not “power steering”, but power steering, and Power Window - not a “window of power”, but electric window lift.
In this article we will look at 7 Key Meanings of the Term power in auto topics, including hidden nuances that even professional services do not translate. You will learn how this word is used in electrical, engine, documentation and even in mechanics' colloquial speech. And at the end - a verification test that will show how well you have learned the material.
1. Power as “power”: technical characteristics of the car
The most common meaning is power. In the context of cars power stands for engine power, measured in horsepower (hp) or kilowatts (kW). For example, the phrase engine power 150 hp translated as "engine power" 150 hp».
It is important to understand that different countries use different power measurement standards:
- SAE (USA) - usually overestimates the figures by 5–10% compared to the European standard.
- DIN (Europe) - more strict, shows real power “at the crankshaft”.
- JIS (Japan) - often indicated in documentation for Japanese cars, may differ from DIN by 3-7%.
- 🔧 Where to look: in the PTS (column “Engine power”), on the nameplate under the hood, in spare parts catalogs.
- ⚡ Nuance: if the documents indicate power in
kW, multiply by 1.36 to gethp(for example,100 kW × 1.36 = 136 hp). - ⚠️ Trap: in the USA they sometimes write horsepower (
hp), and in Europe - metric horsepower (PS). It's not the same thing!
If the power in the documents for a used car from the USA is indicated in hp, and in the Russian PTS - in kW, recalculate the value yourself. Sellers often round numbers in their favor.
2. Power in the names of car systems: what is hidden behind the buttons
On the dashboard or control levers there are often inscriptions with power. Here are the most important of them:
| Inscription in English | Translation into Russian | Where is it used? | What happens if there is a breakdown? |
|---|---|---|---|
| Power Steering | Power steering | Steering column, hydraulic or electric pump | The steering becomes “stiff”, especially at low speeds |
| Power Window | Power window | Doors, buttons on the driver's console | The glass stops going up/down |
| Power Seat | Electric seat | Seat side panels (position adjustment) | Height/angle adjustment does not work |
| Power Mirror | Electrically adjustable mirrors | Door mirrors, driver's door lever | Mirrors cannot be adjusted remotely |
If the indicator light on the dashboard lights up Power Steering Fault, this means power steering fault. In this case:
- Check the fluid level in the power steering reservoir (if the system is hydraulic).
- Inspect the power steering pump drive belt for cracks.
- If the system is electrical (EPAS), check the fuse
F30(usually50A).
How to temporarily drive without power steering?
If the power steering fails, you can go to the service center, but:
- The speed should be above 40 km/h (the steering wheel turns easier while moving).
- Avoid sharp turns - the load on the steering rack increases 3-4 times.
- Do not hold the steering wheel in the extreme position for more than 5 seconds - this may damage the pump.
3. Power in electrics: batteries, generators and wires
In auto electrics power most often means food or electricity. For example:
- Power cable — power cable (for example, from the battery to the starter).
- Power supply — power supply (in radios, rear view cameras).
- Power loss - loss of power (may indicate problems with the generator).
If an error appears in the vehicle diagnostics P0562 (System Voltage Low), this means that voltage in the on-board network is below normal (12.6V with the engine off, 13.8–14.4V when running). Reasons:
- 🔋 Discharged or old battery (capacity below
40%from face value). - 🔄 Faulty generator (does not charge).
- 🔌 Oxidized terminals or poor ground contact.
- 💡 Current leakage (for example, due to an unswitched radio or alarm system).
Once a month|Only when the car won't start|Before winter|Never-->
How to check? Take a multimeter, set it to DC voltage measurement mode (DC 20V) and connect to the battery terminals:
- 12.6–12.8V - the norm.
- 12.0–12.5V - requires recharging.
- Below 12.0V — deep discharge, sulfation of the plates is possible.
If the battery voltage is lower when the engine is running 13.8V, the generator does not charge. This leads to battery drain and electronic failure.
4. Power in legal documents: PTS, insurance, customs
In the car documents power always translated as engine power, but there are some nuances here:
- B PTS power is indicated in kW (for example, 75 kW = 102 hp).
- B OSAGO insurance policy - only in hp (rounded to the nearest whole number).
- B customs declarations may be indicated in hp (SAE horsepower).
Example of discrepancy: in PTS on Toyota Camry 2.5 power indicated 135 kW, which is equal 184 hp. But the insurance may state 183 hp due to rounding. This is not an error, but when checking the traffic police it is better to have both documents with you.
⚠️ Attention: If the power in the title and insurance differs by more than 5 hp, this may be a reason for refusal to pay in case of an accident. Insurance companies consider such discrepancies to be a sign of document fraud.
Also the word power found in statements like:
- Power of Attorney — power of attorney (for example, driving a car).
- Power Unit — power plant (in technical passports for special equipment).
5. Power in the colloquial speech of mechanics and car owners
In informal communication power may mean something completely different from what it says in the documents. Here are some examples:
- 🔧 This engine has no power — “The engine does not pull” (no traction, accelerates poorly).
- ⚡ Power mod — “Chip tuning” (reflashing the ECU to increase power).
- 🚗 Power brake — “Vacuum brake booster” (in old cars).
- 💨 Power loss at high RPM — “Power loss at high speeds” (may indicate problems with the fuel pump or clogged injectors).
If the mechanic says Your car needs more power, he doesn't mean buying a more powerful engine. Most likely we are talking about:
- Cleaning the fuel system (injectors, throttle valve).
- Replacing the air filter (a clogged filter “strangles” the engine).
- Checking the turbine (if the car is turbocharged).

6. Power in the names of spare parts and consumables
The word is often found on parts and packaging power, but its translation depends on the context:
| Inscription on details | Real value | Usage example |
|---|---|---|
| Power Steering Fluid | Power steering fluid | Replace every 60,000 km or when darkening |
| Power Brake Booster | Vacuum brake booster | Checks for leaks when the brake pedal is depressed |
| Power Antenna | Electric antenna (with motor) | Breaks due to icing or mechanical damage |
| Power Relay | Power relay (eg starter relay) | Check with a multimeter for resistance (50–120 Ohm) |
When purchasing spare parts, pay attention to articles - even if the title contains power, the part may not fit. For example, Power Window Motor (window lift motor) for Volkswagen Golf IV not compatible with Golf V, despite the similar name.
⚠️ Attention: On AliExpress and other sites they often sell “universal” parts with the inscription Power (for example, Universal Power Relay). In 80% of cases they are not suitable for specific car models - check compatibility by VIN code.
7. Power in diagnostics and errors of the on-board computer
If the on-board computer gives an error with power, this is almost always associated with electric or motor. Decoding popular codes:
P0100— Mass or Volume Air Flow Circuit Malfunction (malfunction of the mass air flow sensor, “MAF”). Leads to loss of power and increased fuel consumption.P0300— Random/Multiple Cylinder Misfire Detected (misfire). The engine "troits" and loses up to 30% power.P0560— System Voltage Malfunction (unstable voltage in the on-board network). May disable electric power steering.P2101— Throttle Actuator Control Motor Circuit Range/Performance (throttle valve malfunction). The car does not respond well to the gas pedal.
To read errors you can use:
- Diagnostic scanner (eg ELM327).
- Mobile application (for example, Torque Pro for Android).
- Vehicle service menu (on some models errors are displayed on the dashboard display).
To reset the error P0560 (unstable voltage), sometimes it is enough:
- Disconnect the battery for 10 minutes.
- Turn the ignition key to position
ON(without starting the engine). - Wait 30 seconds - the error should clear.
If the error appears again, the problem is in the alternator or wiring.
Errors with power in code (for example, P0562) often indicate electrical rather than mechanical problems. Start your diagnosis by checking the battery and alternator.
FAQ: Frequently asked questions about the translation of “power” in automatic topics
❓ What does the inscription mean Power Mode on the button in the cabin?
This is the mode maximum engine performance (sport mode). Typically disables economy settings, makes the gas pedal more responsive and increases revs when changing gears. It is recommended to turn it on only on the highway - in the city it increases fuel consumption by 10–15%.
❓ The car documents say Power: 90 kW. How much horsepower is this?
90 kW × 1.36 = 122.4 hp. In insurance and PTS they usually round up to 122 hp. If the insurance states 120 hp, this is the permissible error.
❓ It is written on the battery Power 60Ah. What does this mean?
This battery capacity — 60 Ah (amp-hours). The higher the value, the longer the battery holds its charge. Sufficient for most passenger cars 55–70 Ah. If a battery with a capacity of 90 Ah, the generator may not have time to charge it.
❓ The repair instructions say Disconnect power before service. What to do?
This means turn off power before starting work. For car:
- Remove the negative terminal from the battery.
- Wait 5 minutes (so that the capacitors in the electronics discharge).
- When working on airbags, turn off the power to
15+ minutes.
❓ What is it Power Train in the warranty documents?
This power train - a set of components that transmit power from the engine to the wheels. Includes:
- Gearbox.
- Clutch.
- Cardan shaft or CV joints.
- Main gear and differential.
Warranties typically only cover manufacturing defects and not wear and tear from misuse.
