Is your catalytic converter bad?

Every week, we see Queen Creek clients at Wicked Wrench AZ who’ve been told their catalytic converter is shot and needs replacing. Direct-fit cats can cost a fortune—hundreds or even thousands—and sometimes, it’s not even necessary. Let’s save you time and money.

Here’s what we do differently:

1. Diagnose Before You Spend
   Don’t rush to replace your catalytic converter. Bring your ride to our Queen Creek shop, and we’ll run a proper diagnostic to confirm if it’s truly bad or if there’s another issue—like a faulty sensor.

2. Explore Your Options
   If the cat’s fine, we’ll let you know. If it needs work, we’ll discuss custom solutions that fit your budget and performance goals, not just slap on an expensive direct-fit part.

3. Custom Expertise
   Our welding pros can fabricate solutions to keep your exhaust system roaring without breaking the bank. From repairs to custom setups, we’ve got you covered.

Seeing that P0420 code pop up on your 1996 or newer ride? It’s super common across all makes and models, but it doesn’t always mean your catalytic converter needs replacing. At Wicked Wrench AZ in Queen Creek, we dig deeper to save you from costly, unnecessary repairs.

Here’s our process:

1. Thorough Diagnostics
   Before touching your cat, we test every sensor to ensure they’re working, check for exhaust leaks, and inspect the catalytic converter itself.

2. Live Data & Heat Check
   We run a live data feed at idle and perform a heat check to see if there’s a difference across the cat—key indicators of its health.

3. Custom Solutions
   If it’s not the cat, we’ll pinpoint the real issue. If it needs work, our expert welders can craft a solution that fits your budget and keeps your ride roaring.

Don’t shell out for a new converter until you know the facts. Possible causes for the code:

• Leaded fuel was used where unleaded was called for (unlikely)
• A damaged or failed oxygen / o2 sensor
• Downstream oxygen sensor (Ho2S) wiring damaged or connected improperly
• The engine coolant temperature sensor is not working properly
• Damaged or leaking exhaust manifold / catalytic converter / muffler / exhaust pipe
• Failed or under performing catalytic converter (likely)
• The oxygen sensors in front and behind the converter are reporting too similar of readings
• Leaking fuel injector or high fuel pressure
• Cylinder misfire oil contamination
