P0160
Fix within 1-2 weeksYour engine's computer isn't detecting any signal from the oxygen sensor after the catalytic converter on Bank 2. This sensor monitors the exhaust gases.
Code P0160 means your Bank 2 Sensor 2 oxygen sensor shows no activity. Common causes: Bad O2 sensor (80%), wiring issues (15%). Drivability: Yes, safe to drive. Repair cost: $50-$200 DIY, $150-$500 professional.
Can I Drive With P0160?
Yes, safe to drive
No restrictions
Stop driving immediately if: Flashing CEL, loud noises, burning smell, rotten egg smell, significant power loss
Symptoms of P0160
- 1Check Engine Light is on
- 2Slight decrease in fuel economy (not always noticeable)
- 3Vehicle may run rich or lean, but often no noticeable driveability issues
Common Causes of P0160
Parts most likely causing this code, ranked by probability
The oxygen sensor itself has failed and is no longer sending a signal to the engine computer.
80% of P0160 cases are fixed by replacing this part
Damaged wires, a corroded connector, or a loose connection to the O2 sensor prevents the signal from reaching the computer.
15% of P0160 cases are fixed by repairing wiring or connectors
An exhaust leak near the sensor can pull in outside air, causing the sensor to read incorrectly or show no activity.
4% of P0160 cases are fixed by repairing an exhaust leak
A rare internal failure within the engine computer can prevent it from reading the O2 sensor signal.
1% of P0160 cases are fixed by replacing the ECM/PCM
Check These First (Before Buying Parts)
- Visually inspect the Bank 2 Sensor 2 O2 sensor and its wiring for any obvious damage, fraying, or corrosion.
- Check for any exhaust leaks near the sensor. Listen for hissing or feel for escaping gases with your hand (when the engine is cold).
How to Diagnose P0160
- 1Visually inspect the Bank 2 Sensor 2 oxygen sensor and its wiring for any obvious damage, corrosion, or loose connections.
- 2Check for exhaust leaks near the sensor. Listen for hissing sounds or look for soot around exhaust joints.
- 3Use an OBD-II scan tool to view live data for the Bank 2 Sensor 2. Look for voltage readings; a P0160 means it will show 0V or no activity.
- 4Test the O2 sensor heater circuit and signal circuit with a multimeter to confirm power and ground, and to check sensor resistance.
- 5If all sensor and wiring checks pass, consider a professional diagnosis for a potential ECM/PCM issue (this is very rare).
P0160 on Popular Vehicles
Toyota Camry
2007-2024Bank 2 Sensor 2 on a Camry is usually accessible from underneath the vehicle, after the catalytic converter on the exhaust manifold side that corresponds to cylinders 2, 4, 6 (V6 models).
80% fixed by replacing the O2 sensor
Honda Accord
2003-2024For V6 Accords, Bank 2 Sensor 2 is located on the rear bank's exhaust, after the catalytic converter. Access can be challenging due to space constraints, but the sensor is the most common failure point.
80% fixed by replacing the O2 sensor
Ford F-150
2004-2024On V8 F-150s, Bank 2 Sensor 2 is on the passenger side exhaust, downstream of the catalytic converter. These sensors are exposed to road debris and heat, leading to common failures.
80% fixed by replacing the O2 sensor
Frequently Asked Questions
What does P0160 mean?
P0160 indicates that your vehicle's engine computer is not receiving any signal from the oxygen sensor located after the catalytic converter on Bank 2. This sensor is crucial for monitoring exhaust gases.
Can I drive with P0160?
Yes, safe to drive. You can drive your vehicle with a P0160 code, but you should fix it within 1-2 weeks. The primary impact is on your emissions and potentially a slight reduction in fuel economy. There is no immediate risk of engine damage.
Will P0160 clear itself?
No, P0160 will not clear itself. The engine computer requires a consistent signal from the O2 sensor to turn off the Check Engine Light. The underlying issue, usually a failed sensor or wiring problem, must be repaired for the code to clear.
How do I fix P0160 myself?
Start by visually inspecting the Bank 2 Sensor 2 O2 sensor and its wiring for damage. If the wiring looks good, replace the O2 sensor. This typically involves disconnecting the electrical connector, unscrewing the old sensor with an O2 sensor socket, and installing the new one.
How much does it cost to fix P0160?
A DIY fix for P0160 typically costs $50-$200 for a new oxygen sensor. If you take it to a professional shop, expect to pay $150-$500, which includes parts and labor.
P0160 keeps coming back - why?
If P0160 keeps returning after replacing the O2 sensor, the problem is likely not the sensor itself. Re-check the wiring and connector for corrosion or damage. A persistent exhaust leak near the sensor or, in rare cases, a faulty engine computer can also cause the code to return.
Will P0160 fail emissions/smog test?
Yes, P0160 will cause your vehicle to fail an emissions or smog test. The Check Engine Light being on due to this code indicates a fault in the emissions system, which prevents the vehicle from passing inspection.
What's the difference between P0160 and P0156?
P0160 means the Bank 2 Sensor 2 oxygen sensor is showing 'no activity' – the computer isn't getting any signal at all. P0156 means the Bank 2 Sensor 2 oxygen sensor is showing 'low voltage' – it's sending a signal, but it's consistently too low, indicating it's not working correctly.
P0160 on Ford F-150?
On a Ford F-150, P0160 typically points to a failed Bank 2 Sensor 2 O2 sensor. This sensor is located after the catalytic converter on the passenger side of the exhaust. Access can sometimes be tight, requiring the right tools, but the repair process is the same as for other vehicles.
Questions to Ask Your Mechanic
Did you check the live data for the Bank 2 Sensor 2 O2 sensor to confirm no activity?
Good answer: Yes, the scan tool showed a flatline at 0 volts, confirming no signal from the sensor.
What did you find when inspecting the wiring and connector for the Bank 2 Sensor 2 O2 sensor?
Good answer: I checked the wiring harness for continuity and resistance, and the connector for corrosion. Everything looked good, so the sensor itself is the problem.

Intermediate - requires specific tools like an O2 sensor socket and potentially a scan tool for confirmation, but the physical replacement is simple.
Cost of Waiting
Ignoring P0160 means your engine's computer cannot accurately monitor exhaust gases. This can lead to reduced fuel economy and will cause your vehicle to fail any required emissions testing. A $50-$200 O2 sensor replacement now prevents ongoing fuel waste and emissions test failures.
While You're In There...
If you find an exhaust leak near the sensor, replacing the relevant exhaust gasket is necessary to seal the system.
Applying anti-seize to the threads of the new O2 sensor prevents it from seizing in the exhaust pipe, making future removal easier.
Tools You'll Need
- OBD-II Scan Tool
- O2 Sensor Socket (7/8 inch or 22mm)
- Ratchet
- Wrench set
- Jack and Jack Stands (if needed for access)
- Wire brush (for cleaning threads)
- Multimeter (for advanced diagnostics)
P0160 is a common code indicating an issue with an oxygen sensor. The repair is straightforward for most DIYers, and your vehicle will run more efficiently afterward.

Your Next Steps
Step 1: Visually inspect the Bank 2 Sensor 2 oxygen sensor and its wiring. Look for any cuts, burns, or loose connections. Also, check for exhaust leaks near the sensor.
Step 2: If the visual inspection doesn't reveal any issues, use an OBD-II scan tool to confirm the sensor is indeed showing no activity. If you have a multimeter, test the sensor's heater circuit and signal wire.
Step 3: If the sensor is confirmed faulty, purchase a new Bank 2 Sensor 2 oxygen sensor. You'll likely need an O2 sensor socket for removal and installation.
