Question about 2001 Toyota Camry

01 toyota camry

Howdy! ive got a 2001 toyota camry, 2.2 4cyl, automatic. my scanner shows a p0401 Exhaust Gas Recirculation Flow Insufficient Detected.. very rough growl at idle, i assumed it was a smog pump mounted on the exhaust side just under the manifold mounted to the front cover, looks like its driven by the timing belt.. sounds like its coming from that. i was informed this year does not have a smog pump... wondering if you knew what this was or have heard of anything in the past.. Thank you! - michael

Hi Mike.

You have 2 issues, and you really need to get the growl issue checked ASAP. What your noise is, is probably a bad water pump. I change them daily. Just did one this morning. The water pump is driven by the timing belt. If the pump locks up, you will ruin the belt, and the car will not restart. Get it checked, replace the pump.

On the P-0401, you have a blockage in the EGR valve, or the tube going to it is carboned up. This is another common issue.

Please let me know about the pump.
A FixYa rating for my assistance would be greatly aappreciated.
Thnaks in advance.

2001 honda odyessy has the following trouble codes: P1491, P0401,P1739. It has also been turning over longer before starting and has cut off while in park and idling. What does this mean?

P1491= "exhaust gas recirculation valve insufficient lift."
P0401= "exhaust gas recirculation insufficient flow"
P1739= ""3rd clutch pressure switch" (automatic transmission code)

the exhaust gas recirculation (EGR) valve is vacuum operated. there may be a vacuum line that is broken or leaking or become detached from the EGR valve. any vacuum leak will cause the engine to run lean, leading to poor starting and idle cut-off due to lean fuel fuel mixture.

The EGR valve has a vacuum diaphragm inside it. this diaphragm could be leaking. the EGR valve will need to be replaced if this is the case.

The P1739 code shows that a problem with the 3rd clutch pressure switch or the wiring leading to the switch has been detected. It may be an intermittent fault. Reset the trouble codes and drive for a while and see if this code returns. If so, check the wiring and switch operation of the 3rd clutch switch.

Check light on,problem shows on p 0401

P0401-Insufficient flow in the exhaust gas recirculation system (EGR-valve). Check your gas cap for cracked seal, check EGR valve (make sure all vacuum hoses aren't leaking), check also VSV (vacuum switching valve) for proper operation. Its best to get an owner's manual or an experienced mechanic to diagnose!!hopefully this helpd
