My RR 2004 is giving me this code my mechanic has scanned it twice and cleared, this just started after the deep freeze we had in the East coast. Any thoughts?

That is not a standard code... no clue. P0122 is usually a TPS sensor gummed up or failing.

For EAS suspension inactive can be anything from a leak overheating the compressor or the compressor not proving pressure to the tank. usually you get the dash error that EAS will resume when it cools off... or whatever the message is... before it goes full inactive. could be invalid articulation from a sticky sensor. Could be a sticky cross oer valve due to your dryer wearing out and moisture in the system.

Sorry to be so vague but real diagnostics or even something basic like RSWs EAS kit would give the real EAS error code being logged.

OK it was reset again yesterday and still ok no suspension inactive message and is working fine now. It was wickedly cold in the East coast so lets hope its stays ok. Tks for your input.
