P0430 on Ford: Recall 24E04, Bulletins and What to Check

What makes P0430 different on Ford?

The code means the same thing on a Ford as on any V6 or V8. The powertrain control module (PCM) compares the oxygen sensors before and after the Bank 2 converter and sets P0430 when that converter looks weak. Our main P0430 guide explains the test and how Bank 2 differs from Bank 1.

What is different is that Ford has formally said the test itself was too sensitive on some trucks. In September 2024 Ford told dealers about Emission Recall 24E04 for certain 2022 to 2023 F-150 Hybrid trucks with the 3.5L PowerBoost engine, built at Dearborn from September 15, 2021 through November 16, 2023, about 90,892 vehicles in the U.S. Ford says the OBD system on these trucks may falsely set P0420 or P0430, so the light can come on even though a converter repair may not be necessary ^[1]. You can read the recall on NHTSA's document server, static.nhtsa.gov.

The dealer reprograms the PCM and, only if the converter falls below the new calibration's efficiency limits, replaces one or both converters, at no charge for parts or labor. Ford's owner letter adds that you qualify even if non-Ford parts or shops serviced the truck before.

Why a reprogram can fix a converter code: the PCM decides what counts as a weak converter. If that limit or the way it is measured is too strict, a healthy converter fails the test. New software changes the test, and then the truck has to complete a drive cycle so the catalyst monitor can run again under the new rules. Ford's letter warns that the dealer may need to drive your vehicle to complete the repair ^[1].

Which Ford vehicles have a P0430 bulletin or recall?

These are the NHTSA-hosted Ford documents for P0430 we reviewed. Your VIN decides what applies.

Document	Vehicles	What Ford says	Action
Emission Recall 24E04	Certain 2022 to 2023 F-150 Hybrid, 3.5L PowerBoost	OBD may falsely set P0420 or P0430	Reprogram PCM; replace converters only if required; free
TSB 25-2233	2022 to 2023 F-150, 3.5L PowerBoost	Calibration and controls sensitivity	Reprogram PCM, catalyst stabilization drive cycle
TSB 25-2549	2021 to 2022 Super Duty, 7.3L	PCM software; does not affect drivability or durability	Reprogram PCM, drive cycle, normal diagnosis if codes return
TSB 25-2382	2021 to 2022 F-650/F-750, 2020 to 2021 F-53/F-59, 2021 to 2022 E-Series, all 7.3L	Incorrectly illuminated light from PCM software	Reprogram PCM, catalyst drive cycle

Sources for the table: TSB 25-2233 ^[2], TSB 25-2549 ^[3] and TSB 25-2382 ^[4]. Not sure which engine your truck has? Our VIN decoder shows the basics.

Is it safe to drive a Ford with P0430?

Usually yes, in the short term. For the Super Duty 7.3L, Ford's bulletin says the condition does not affect vehicle drivability or durability ^[3]. That is reassuring, but it applies to that software issue, not to every P0430.

Two warnings. If the check engine light flashes or the engine shakes, pull over and stop driving, because a misfire can overheat the converter; see P0300 and our guide to a flashing check engine light. And do not sit on a recall: Ford's recall notice says an unrepaired truck may not pass emissions tests, and that California and Massachusetts require emission recall repairs to be completed before registration renewal ^[1]. California's Smog Check also fails any vehicle with the check engine light on ^[6].

One practical note from the recall paperwork: Ford told dealers that trucks without a current or recent check engine light can often get the reprogram as a mobile repair, while trucks with the light on need a shop visit, since the converters may have to be tested and replaced. Mention the light when you book.

How do you check P0430 on a Ford?

Start with the cheapest step, which on a Ford is often a phone call to a dealer.

1. Read every code and save the freeze frame. A scanner that shows live data and freeze frame is enough; see how to use an OBD2 scanner. P0420 and P0430 together fit the Ford bulletins, which list both codes. A lean code on Bank 2 such as P0174 points elsewhere.
2. Ask a Ford dealer to check the VIN for open recalls and bulletins.
3. If a bulletin applies, the dealer reprograms the PCM with Ford's current software and runs a catalyst drive cycle. TSB 25-2233 calls it a catalyst stabilization drive cycle ^[2].
4. The codes are checked again. Under TSB 25-2549, if P0420 or P0430 returns after the reprogram and drive cycle, the technician moves on to normal diagnosis ^[3].
5. If no bulletin applies, use the normal P0430 path: compare fuel trims and rear sensors between banks, look for leaks on the Bank 2 side, test the rear sensor, then the converter.

PCM programming and converter work are dealer or qualified technician jobs. Your part is getting the codes, the VIN and the right questions to the service desk.

How do Ford P0430 causes compare with the usual ones?

The usual P0430 causes still apply to Fords: a worn Bank 2 converter, a faulty Bank 2 rear oxygen sensor, an exhaust leak before or between the sensors, long-term rich or lean running, and an engine burning oil or coolant ^[5]. On a covered Ford, P0420 and P0430 appearing together fit the software pattern better than two worn converters, because a calibration problem affects both banks the same way. A lone P0430 on an uncovered truck points back to the Bank 2 side.

	Generic P0430	Ford documented cases
Likely cause	Converter, sensor, leak or engine fault	OBD calibration or PCM software
Codes	P0430, sometimes with fuel trim or misfire codes	P0420 and/or P0430
First fix	Diagnose, then repair the cause	PCM reprogram and catalyst drive cycle
Parts	As diagnosed	Converters only if needed after reprogram
Who pays	Owner, unless under warranty	Ford, for recall 24E04; warranty terms for TSBs

What does a Ford P0430 repair cost?

If your truck is in Emission Recall 24E04, the reprogram and any required converter replacement are free ^[1]. The 2025 bulletins say the repairs are eligible under Ford's new vehicle limited warranty, emissions warranty and related coverage, with limits set by the failed part. Federal rules give catalytic converters an 8-year or 80,000-mile warranty period on light-duty vehicles ^[7]; heavier trucks such as the Super Duty and F-650/F-750 may fall under different rules, so ask the dealer what applies.

Outside coverage, we found no Ford-specific price source we trust. The cost depends on what testing finds: a software update is short labor, while converter replacement on a truck can mean removing heat shields and crossmember hardware, as the parts lists in these bulletins show. Get a written estimate that names the failed part and the test that found it.

After any repair, clearing the code does not fix anything, and inspection stations check readiness monitors. Never consider removing or disabling emissions equipment; tampering is illegal under the Clean Air Act ^[8]. Other Ford codes? Try our code lookup, or compare with the Bank 1 code in our P0420 guide.
