The hourly rate is the BLS Occupational Employment and Wage Statistics, May 2025 average pay for this trade in the US, $27.13 an hour, times 4 to 5.5 to cover what a shop bills (overhead, tools, insurance, profit). Parts are a band from budget aftermarket to the manufacturer part. Full method.

This is the range for the most common fix, oxygen sensor replacement (one sensor). Which repair your car needs depends on a proper diagnosis.
The oxygen sensor in front of the catalytic converter on cylinder 1's bank is sending a very high voltage, which normally means a rich mix. If the sensor is telling the truth, the engine is getting too much fuel. If not, a shorted wire or a failed sensor is making it look that way.
- Safe to drive?
- Short trips only
- Most common cause
- Failed upstream O2 sensor
Safe for short drives. Fix soon, since it can foul plugs and waste fuel.

Fair Price is not a contractor or a repair shop. Who sees your request
What you may notice
- Poor fuel economy
- Rough idle
- Black exhaust smoke
- Check-engine light
Common causes, most likely first
- Failed upstream O2 sensor
- Wiring shorted to voltage
- Real rich condition from a leaking injector
- Fuel pressure regulator problem
Check this first
Ask the shop to check fuel trims first. If trims are normal, the sensor itself is at fault.
Other repairs that sometimes fix P0132
| Repair | Typical range, US |
|---|---|
| Fuel injector replacement (one injector) | $170 to $820 |
| Diagnostic scan (check engine light) | $55 to $250 |
Before you pay
- Ask the shop what test showed this part is the cause, not just that the code appeared.
- Ask for parts and labor listed separately, and for the hours.
- Ask for a written OK before any extra work. Many states require written authorization before repairs.

P0132 questions
Is the sensor or the engine at fault?
Fuel trim readings help tell the difference. If trims show the computer pulling fuel away, the engine really is rich. If trims look normal, the sensor or wiring is probably the issue.
How much does the sensor matter?
The upstream sensor guides the fuel mixture, so a bad one hurts fuel economy and emissions. It also affects how smoothly the engine idles, so it is worth fixing within weeks.
Can I clean it?
Cleaning rarely works. The sensor tip is a ceramic element and any deposits or damage inside it are not removable. Replacement is the usual fix and is a modest job on most cars.
How much does it cost to fix P0132?
The most common fix, oxygen sensor replacement (one sensor), has a typical range of $100 to $350 across the US. It is an estimate built from parts prices and local labor wages, not a quote. Your car and shop change it.
