P2032 code meaning
Exhaust Gas Temperature Sensor Circuit Low (Bank 1 Sensor 2)
Powertrain system Generic code P20xx codes Check engine light
What P2032 means
P2032 means the signal of exhaust gas temperature sensor 2 on bank 1 is below its valid range. What that means electrically depends on the sensor type. On the Opel/GM 2.0 CDTi in the Saab 9-5 (2010) sensor 2 sits in the particulate filter and its voltage falls as it gets hotter, so a reading below 0.4 V for more than 1 s points to a short to ground; the code is Type A there. GM's 2009 Duramax uses the opposite characteristic and fails below 0.307 V, equivalent to -40 °C, for 300 s, which is typical of an open or grounded signal. GM's 2018 diesels compare against a resistance-equivalent limit below 142 Ω as a Type B code, Ford's 2023 diesels against 0.10 V within 2 s. So check the wiring diagram before deciding whether low means a short or an open. Without the sensor the ECM cannot control filter temperature and usually blocks regeneration.
P2032 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyMedium, DIY possible
- Typical labor0.3 to 1.5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2032
- Malfunction indicator lamp on
- DPF regeneration inhibited, soot load rises
Common causes of P2032
- Most likelySignal wire chafed to ground on the exhaust
- PossibleInternal sensor failure
- PossibleDamaged or corroded connector
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2032 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 0 | Area: fuel and air metering and auxiliary emission controls. |
| 32 | The exact fault in that area. |
What to do next
- Note P2032 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P2032
What does P2032 mean?
P2032 means "Exhaust Gas Temperature Sensor Circuit Low (Bank 1 Sensor 2)". P2032 means the signal of exhaust gas temperature sensor 2 on bank 1 is below its valid range. It is a generic code, so it means the same on every make.
Is it safe to drive with P2032?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will P2032 fail an emissions test?
Yes, it can. P2032 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P2032 to fix?
Difficulty: medium. A typical repair takes 0.3 to 1.5 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P2032 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
