P2074 — MAP/MAF — Throttle Position Correlation at Higher Load
CAUTIONIs it safe to drive? Drive gently and get it looked at soon — it can worsen or fail inspection.
What P2074 means
This is a manufacturer-specific code — its meaning depends on the vehicle’s make (see below).
What P2074 means on specific makes
Dodge / Jeep / Ram / Chrysler CAUTION
Generic SAE but common on Chrysler/Jeep electronic-throttle engines. A rationality check: the MAP (or MAF) reading doesn't agree with the throttle position under higher load. Often a vacuum leak or a failing MAP/TPS rather than a serious mechanical fault. Can cause hesitation or reduced power.
- Large vacuum leak ($0-200)
- Failed MAP sensor ($30-120)
- Failed throttle position sensor / dirty throttle body ($0-30 clean, $150-350)
- Wiring fault ($20-150)
Check first: Smoke-test for vacuum leaks first; compare MAP and TPS live data under load for the mismatch.
