P2087: Exhaust Gas Temperature Sensor Circuit Intermittent (Bank 2 Sensor 2)
The EGT sensor at bank 2 sensor 2 signal jumps or drops out intermittently — typically a connector or chafed wire near the exhaust manifold heat zone.
What P2087 means
P2087 is a generic OBD-II powertrain code in the emissions group. In plain English: the computer found an electrical fault in that circuit: an open, short or bad connection, or a failed component. Bank 2 is the side of a V or flat engine opposite cylinder 1.

Common causes
- 01Connector looseMost likely
- 02Connector with intermittent contact under vibrationLess likely
- 03Harness routed against vibrating componentLess likely
Can I drive with P2087?
Usually yes, for a short time.
The car will often drive normally, but get it diagnosed soon. Left alone it can raise fuel use and emissions and will fail an OBD inspection. If you notice rough running, warning lights flashing, overheating or a burning smell, stop driving.
Why we rate it moderate
- Turns on the check engine light
- Emissions-related: will usually fail an OBD inspection
Severity is our rule-based rating from the code’s flags in OBDex and the system it affects, not an inspection of your car. If the check engine light is flashing, or you notice overheating, low oil pressure, or brake or steering problems, stop driving and get help.
How to diagnose P2087
- 1
Confirm the code and save freeze-frame data
Read the codes with an OBD-II scan tool and note every code, not just P2087. Save the freeze-frame data (speed, load, temperature when the fault set) before clearing anything; it tells you when the fault happens.
- 2
Check for related codes first
Look for P2081, P2085, P2083. Related codes often share a cause; a circuit or sensor code usually needs fixing before a performance code like this one.
- 3
Test the circuit
Inspect the wiring and connector at the exhaust gas temperature sensor for damage, corrosion or chafing. With a multimeter, check supply voltage, ground and signal against the specifications in the service manual for your vehicle.
- 4
Test the likely causes in order
Start with the most likely cause and work down: Connector loose; connector with intermittent contact under vibration; harness routed against vibrating component. Test before replacing parts.
- 5
Check for recalls and service bulletins
Look up recalls for your exact vehicle with its VIN, and ask a dealer about technical service bulletins (TSBs). Manufacturers sometimes issue software updates or extended warranties for known faults.
- 6
Clear the code and verify the repair
After the repair, clear the code and drive the car under the conditions in the freeze-frame data to confirm it does not return.

P2087 FAQ
What does P2087 mean?
P2087 means “Exhaust Gas Temperature Sensor Circuit Intermittent (Bank 2 Sensor 2)”. The EGT sensor at bank 2 sensor 2 signal jumps or drops out intermittently — typically a connector or chafed wire near the exhaust manifold heat zone.
Is P2087 serious? Can I keep driving?
We rate P2087 as moderate severity. Usually yes, for a short time. The car will often drive normally, but get it diagnosed soon. Left alone it can raise fuel use and emissions and will fail an OBD inspection. If you notice rough running, warning lights flashing, overheating or a burning smell, stop driving.
What causes P2087?
The most common causes, from most to least likely: Connector loose; Connector with intermittent contact under vibration; Harness routed against vibrating component. Test before replacing parts, because several causes can set the same code.
How much does it cost to fix P2087?
Typical labor is about $65–$250 at an assumed $125/hour shop rate, plus parts. That is an estimate, not a quote: labor times and rates vary by vehicle and region, and diagnosis may be billed separately.
Can I fix P2087 myself?
DIY difficulty is moderate. Many owners can handle it with a scan tool, a multimeter and basic hand tools. Always confirm the cause before buying parts.
Will P2087 clear itself?
If the fault was intermittent, the warning may go off once the computer stops seeing it, but the code stays in memory. Fix the cause; clearing the code alone doesn’t repair anything.
