What P2035 means
P2035 reports that the signal of temperature sensor 2 on bank 2 has dropped below its plausible floor. Whether that is a short or an open depends on the sensor curve: with a thermistor pulled up by the control unit a grounded wire drags the voltage down, whereas some circuits read near zero when the loop is broken. No manufacturer documents P2035 publicly. Deutz, the one maker found using this sensor slot, keeps the short to ground under P2034-11 instead. The bank 1 counterpart P2032 shows typical limits: GM's 2018 diesels fail below a resistance equivalent of 142 ohms as a Type B code (MIL after two trips). CARB requires such out-of-range checks for every emission-relevant input. Expect the dosing or regeneration strategy that relies on this reading to be cut back.
P2035 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 P2035
- Engine warning lamp on
- Temperature reading on bank 2 implausibly low or at the limit
- Regeneration or DEF dosing limited
Common causes of P2035
- Most likelySignal wire chafed through to ground on the exhaust or frame
- PossibleInternal short in the sensing element
- Less likelyWater bridging the connector pins
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2035 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. |
| 35 | The exact fault in that area. |
What to do next
- Note P2035 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 P2035
What does P2035 mean?
P2035 means "Exhaust Gas Temperature Sensor Circuit Low (Bank 2 Sensor 2)". P2035 reports that the signal of temperature sensor 2 on bank 2 has dropped below its plausible floor. It is a generic code, so it means the same on every make.
Is it safe to drive with P2035?
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 P2035 fail an emissions test?
Yes, it can. P2035 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 P2035 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 P2035 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
