2000 Jeep Grand Cherokee P1494 Error: Leak Detection Pump Switch Fault - How to Fix
Hi there, I'm experiencing a P1494 error code on my 2000 Jeep Grand Cherokee: 'Leak Detection Pump Sw or Mechanical Fault - Incorrect input state detected for the Leak Detection Pump (LDP) pressure switch'. Does anyone with hands-on experience have successfully repaired this issue themselves? Any guidance on diagnosis or repair steps would be greatly appreciated. Thanks in advance!
This is a common fault found in Jeep Grand Cherokee and Chrysler vehicles. The most effective solution is typically replacing the Leak Detection Pump (LDP) unit.
