Dodge Journey: Throttle body failure on the 2.4 — clicking on ignition, then limp mode

The throttle body on the 2.4 Journey fails, and it gives an unusually specific early warning: an odd clicking noise from under the bonnet when the ignition is first switched on, as the electronic throttle tries and fails to run its self-test. From there it progresses to a rough idle, hesitation, and eventually the car dropping into a reduced-power mode that limits you to walking pace — which is safe enough in a car park and unpleasant on an open road. It is a bolt-on part rather than a major repair, so this is a cost to price in rather than a reason to walk away, but it strands people, and the clicking is something you can hear in the first ten seconds of a viewing if you know to listen for it.

• Clicking or buzzing from under the bonnet when the ignition is switched on
• Rough or hunting idle, or the engine stalling
• Hesitation or no response when you press the accelerator
• Engine warning light, or a reduced-power mode limiting speed
• Throttle or electronic throttle control warning on the dash

1. 1

   Listen at the very start, before the engine is running.

2. 2

   Turn the ignition to the on position without cranking, stand at the front with the bonnet up, and listen for a repeated clicking or buzzing from the top of the engine — a healthy throttle body runs its self-test almost silently, and a persistent clicking there is this fault announcing itself.

3. 3

   Then start it and watch the tachometer at idle for revs that hunt up and down or a needle that will not settle, and listen for any stumble.

4. 4

   On the drive, press the accelerator gently from a standstill several times and note whether the car responds immediately or hesitates, and watch the dash the whole time for an engine warning light or a throttle control message.

5. 5

   Note any moment where the car limits its own speed.

6. 6

   Ask the seller whether the throttle body has ever been cleaned or replaced and whether the car has ever gone into limp mode.

7. 7

   If a workshop inspection is possible: ask for the stored throttle-position faults to be read.

$400 to $1,400 at New Zealand independent workshop rates. That is for this job on its own, not for the car.

An estimate, in NZD, for the repair as normally carried out. What a specific car costs depends on which part has failed and what it damaged on the way — treat this as the floor for a negotiation, not a quote.

• “Has the throttle body ever been cleaned or replaced?”
• “Has the car ever gone into a reduced-power mode?”
• “Does it ever hesitate or stall when pulling away?”

The failure described above is documented in published sources — owner forums, technical service bulletins, recall notices and workshop write-ups — held in our fault database. The inspection instructions and the cost estimate are KickTyres’ own interpretation of them, and it is a starting point for an inspection rather than a manufacturer statement.
