What's wrong?
The engine wiring harness on the 2022 Isuzu N-Series is the bundle of wires that carries electrical signals between the engine and its sensors. On these 6.0L gasoline trucks, that harness connects to the oil pressure sensor, which tells the engine computer whether the engine has enough oil pressure to run safely.
In affected trucks, the wires for pin positions 2 and 3 at the oil pressure sensor connector were reversed because of an engineering drawing error. That reversal means the sensor circuit is not connected the way Isuzu designed it. The truck can respond with engine protection behavior, including reduced speed operation, or the engine can stop.
Owners can see a Check Engine Light, an Engine Overheat Warning Light, knocking or clicking engine noise, or limited speed operation. If the truck goes into limited speed operation, park it as soon as possible. Some trucks stop with no warning sign before failure.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific truck is included.
What's the safety risk?
An incorrectly wired oil pressure sensor can leave the driver without a low oil pressure warning. That can lead to an engine stall and increase crash risk. If you see the Check Engine Light or Engine Overheat Warning Light, hear knocking or clicking, notice limited-speed operation, or the engine stops, park as soon as safely possible and call the dealer. Repair will be free at any franchised Isuzu dealer once available.
What should I do?
- Check your VIN to confirm your 2022 Isuzu N-Series is included in this recall.
- Contact a franchised Isuzu dealer before scheduling service, since the remedy status is not listed as available.
- Ask about the free wiring-harness connector repair that restores the low-oil-pressure warning from the oil pressure sensor.
- Bring the Isuzu owner letter if you have it. If not, reference recall number 22V434 when you call.
- Stop driving and contact the dealer if the truck stalls or shows signs of low oil pressure before the repair.
What happens at the repair
Once the repair opens, an Isuzu technician will correct the engine wiring harness assembly connector at the engine oil pressure sensor. The issue is that the harness was wired incorrectly to that sensor, so the dealer repair focuses on fixing that connector and wiring path. Parts and labor will be covered under the recall. Isuzu has a general reimbursement plan on file for owners who already paid for a related repair before the recall notice. Keep your repair paperwork and ask Isuzu customer service or the dealer how to submit documented expenses.

Frequently asked questions
What is recall 22V434?
Recall 22V434 covers 974 2022 Isuzu N-Series Gas trucks with 6.0L engines. The engine wiring harness was incorrectly wired to the oil pressure sensor, so the driver will not get a low-oil-pressure alert before an engine stall. Isuzu dealers fix the connector for free.
What should I do if my 2022 Isuzu N-Series is on this recall?
Check your VIN to confirm your specific truck is included in recall 22V434. If it is, call a franchised Isuzu dealer and reference recall 22V434 or Isuzu recall V2202. Ask the service desk to confirm the wiring-harness connector repair and appointment timing.
Is the recall repair free?
Yes. Federal recall law requires the manufacturer to repair the defect at no cost, and Isuzu's remedy says dealers will fix the engine wiring harness connector at the oil pressure sensor free of charge.
What is the safety risk?
The risk is that the oil pressure sensor wiring will not warn the driver when oil pressure is low. Without that warning, the engine can stall, increasing crash risk. If your VIN is included, arrange the free connector repair with a franchised Isuzu dealer.
What if I bought my Isuzu N-Series used?
The free recall repair still applies. Recall coverage follows the VIN, not the first owner. Check your VIN, then contact a franchised Isuzu dealer with recall 22V434 or Isuzu recall V2202. Isuzu customer service is also available at 1-866-441-9638.
